Lasers are cool. They can be used for so many applications, from LIDARS and spectroscopy to laser scanning to laser cooling. Now, lasers made from sound - which could in theory create more precise images than their light-based counterparts - might be on the horizon. Let’s take a look.

Amplification of Sound by Stimulated Emission of Sound... Oh wait!
The whole point of the device is that the emission is not noise, but is instead coherent sound. Thus, your acronym is faulty.
Given the historical evolution of the acronym LASER (Light Amplification by Stimulated Emission of Radiation) from its precursor MASER (Microwave Amplification by Stimulated Emission of Radiation) in which the type of radiation emitted is given by the first word in the acronym, SASER (Sound Amplification by Stimulated Emission of Radiation) or PASER (Phonon Amplification by Stimulated Emission of Radiation) would be more in keeping with the historical naming tradition.
The paper that Sabine references calls the devices Phonon Lasers, but that is not satisfactory since that term could be misinterpreted as indicating that laser light is being produced or amplified by phonons in the devices, which is not the case.
However, the paper's use of the term phonon in referring to the devices, makes me prefer the acronym PASER over SASER.

Jazz has been doing that for a century now!
Cool stuff. Can I scale the sound waves larger?
@@TheSonorabob sure, just lower the frequency.
I did this in grad school, with a tuned cavity that used unstable combustion of a fuel/oxygen mixture (as in a rocket) as the active medium, back in the late 1970s.
That's so cool. I'm glad to see you are still with us.
Wait...what happened in your experiment?
When I was a kid, watching the hand blasters in science fiction movies, I imagined using the pistol shaped butane soldering torch that Radio Shack sold to make a gas combustion laser...

Can't believe that at your age you watch this biased superior arrogant "scientist"
1:40 A little bit non-obvious but okay, I get it. The wavelength of light at 1 kilohertz will be about 3*10^5 meters. The wavelength of sound at 1 kilohertz is about 1/3 meter.
That threw me too until I considered the absurdly large antennas used for LF radio work.
Intuitively, a frequency of 1 kHz translates to a speed of 1000 wavelengths per second. A greater speed would result in the wave passing through a greater distance per second, a greater distance to be divided into thousandths
If this can help with my ringing ears. That would be awesome!
if you're serious i think hearing aids can eliminate ringing these days.
For a lucky few where it cancels out the noise frequency.

@@HarryNicNicholas Nah, hearing aids just amplify sounds. Tinnitus, or "ringing in the ears", is caused by the cilia (the tiny hair-like structures in the cochlea) laying flat instead of standing up. There's been some research into the junction between the base of the cilia and the nerve it connects to -- it has to do with something chemical (biology isn't my field -- I'm a retired computer and electrical engineer). Being a military vet (Navy), I live with service-connected tinnitus, which is annoying at best. If I had the proper audio equipment, I could recreate exactly what I hear 24/7/365. It's not a "ringing" tone, rather several higher-pitched frequencies that fluctuates a bit and there are also some seemingly random quick pulses. The particular frequencies that I can no longer hear (or, at least not well), happen to be at or close to the hiss-like tones being generated by the damaged cilia (or the base of the ones affected). When I listen to music, I run the audio through a 30-channel graphic equalizer program on my computer so I can boost the specific higher-range sounds and tone-down the lower frequencies.
Its what you are eating...took me years of non-stop tinnitus to accept it...for me its nitrates, sulphites and other preservatives. I had to cut out all meat exept fresh cut.
We should call it saser, instead of laser
Laser, saser, tazer, razors and light-sabers 🏹⚔️✂️📌🪒💉
"Phonon laser" = Phaser. Obviously.
It is not radiation, unless you define it more broadly than the sense in which it is typically meant. But @brothermine2292 is right, phaser is most likely to stick, if someone associated with the research proposes it, even though the actual output will technically be neither phonons nor radiation.
Souser hehe, saucer, sauce laser
@@brothermine2292 = Plaser
This has serious ramifications for sonar.
I thought that was sonor was lol
@@SupCortez No, not really. Sonars do not make the same noises they did during WWII. Soviet sonar would often sound like blocks of wood being banged together--or so I have read--but SADAR would be something entirely new.
@@ManuelGarcia-ww7gj One of the STs (SONAR technicians) I knew while I was in the Navy told me that the Soviet subs sounded like taking a 3-lb coffee can, half fill it with gravel, and then shake it vigorously. They could be heard a long way off. Btw, my berthing compartment was below the waterline so we got to hear our bathometer (used to determine depth) whenever we were in coastal areas -- it was irritatingly loud and high-pitched.
Possibly even more serious ramifications for whales!
And thus for submarines and thus for national security.
Thank you for very nice and simple explanation.

Only in the film, the book has no such weapon, fyi.
The are longitudinal waves are phonons also longitudinal?
Depending on the medium, phonons can be both transverse and longitudinal.
@@SabineHossenfelder Thank you!
@@SabineHossenfelderyou do know that we can send sound via certain frequencies and have tuning forks that will pick up those frequencies and resonate... So basically you could transfer energy and sound through the tuning forks from one to the other completely wirelessly...
@@AquarianSoulTimeTravelerthat's true of electromagnetic radiation as well. You can wirelessly charge or power things using radio or microwaves, but we don't use this for long range power transfer because of transmission loss and the inconvenience of dumping energy into things that are in the way. The same would be true of power transfer through sound.
@@johnmorrell3187 that's kind of the angle I figured... I agree. Just pointing it out.
This technology might work well with sonogram or ultrasound tomography. I know a PhD was completed at Bern University on ultrasound tomography. That is looking through tissue with ultrasound rather than reflectance to measure tissue density and structure. Highly focused ultrasound might improve ultrasound tomography.
For instance looking through uncompressed breast tissue might be a better experience for patients and provide better information. Let's hope
"That is looking through tissue with ultrasound rather than reflectance to measure tissue density and structure" There is something missing in this sentence working with ultrasound is exactly what classical Sonography is about..
@@georgelionon9050 Hi. classical sonography {your term) looks at the reflectance patterns of ultrasound waves that are projected into soft tissue. The work I was referring to interprets pass-through scattering patterns, the analogy being "like an Xray." There are good papers discussing this technology available using google scholar.
Buzz kill. Ha
Pfft, My mother-in-law has used sound-lasers as a weapon for years... just listen to her! :-)
Shriekers are worse than ass blaster graboids for sure.
Kanye West ... the parallel we deserved by our dumb comments ...
I thought sound lasers (called SASERs or PhASERs) already exist. I did experiments with it in undergrad physics like 5 years ago. This fell under the physics fields of thermoacoustics, and is related to acoustic refrigeration/heat engines/cycles. We had a ceramic material with hexagonal honeycomb shape/gaps placed inside a test tube with similar dimensions to the inside of the test tube close to the closed end of the tube. When you apply enough current through it, it creates sound caused by difference in temperature on the closed end of the tube to the open end of the tube. And it did all the things that this experiment did but couldn't form a beam.
Yea, Sabine's coverage of anything outside high energy particle physics or solutions to GR should mostly be taken with as much authority as Popular Science. Non-expert summary and expansion on the title, first 2 sentences of the abstract, and first two sentences of the conclusion of a paper that looks interesting. If it sounds interesting, link to the paper is available in the description.
This is very much an incremental improvement on techniques which might hold promise for better volume and narrowed linewidth. As to focusing, that is a function of linewidth. Lensing and reflection of any wave is frequency dependent, so the fewer and closer the frequencies involved, the better it can be focused.
I think those are more like focused beams of sound than really lasers. The frequency is much more discrete in this paper.
@@vidal9747 Ohhh, I see.
A sound "laser" will decohere if they try to transmit it through the air. This is because sound travels as a p-wave through gasses and liquids. Light is an s-wave and can remain coherent indefinitely. To keep the sound beam coherent, they would have to transmit it as an s-wave through a solid, crystalline substrate such as steel, because as soon as it hits the air, it would just turn into noise.
What's your education background?

@@kublai4434 Beauty school dropout. 😎
@@Naomi_BoydAnd you wonder why 90% of YT views are by males.
Professional sound engineer here - air is a very poor medium for the transmission of high frequencies. Amplitude drops off very quickly with distance. The higher the frequency, the more it is attenuated.

A sphere vibrates in a vacuum ... does it make a sound? I presume they at least tried this in an actual medium.
sound actually only exists inside your brain and even there it's only simulated, there is no noise. when you clap your hands you just create different pressures in the air, there is no "noise". same with colout, photons are particles, they have no intrinsic colour, your brain take the energy level and wavelength and ASSIGNS it a colour. otherwise things like red shift wouldn't happen.

People with excessive knowledge claiming to be intelligent, sure know how to reduce intelligence to an incomprehensible pile of manure so deep, you can blame it on a bull.
@@scotttovey I mean, sure, Harry might be overcomplicating things, lol. But it’s fun to think about! Without our human sensory organs and brain, what would the universe look or sound like?

@@Anonymous-df8itI don’t think it makes sense to say that the *color* is defined by the energy level? Color is imo unlike pitch/frequency, in that color is more specific to the way we perceive things, while for pitch, that’s more about the actual what’s-going-on ?
I mean, I guess we *could* reserve “pitch” and “sound” for specifically our perception of it, but I don’t see the point of that,
while for color, we talk about different combinations of wavelengths as being the same color all the time, if they are indistinguishable to human eyes, so the way we use the word “color” is I think already referring to human perception.
I guess we could also say that the “pitch” of a sound is about our perception, while the “frequency” is the actual physical quantity, but, maybe I’m mistaken in this, but I think our perception of sound corresponds to the physical properties well enough that this is unnecessary.
(We don’t filter sound into 3 (or 4) buckets based on frequency.)
In use since the early 1980s, _lithotripsy_ treats kidney stones by sending focused ultrasonic energy or shock waves directly to the stone. The shock waves break a large stone into smaller stones that will pass through the urinary system. The technique is also used on gall stones and other hard masses.
Brilliant insight. Optical tweezers have been around maybe 40 years and this is the most creative use I've seen. They made a simpler device, with deeper understanding. New minds, from Hunan.
Also good food
If phonons can manipulate light, I wonder if we will see phonon based, free-standing holograms?
To manipulate individual phonons you generally need them to be in a very cold medium. (AIUI thermal vibrations can also be described with phonons, and so when something isn’t super cold, there are many many phonons, and can’t do much with them?)
Also, the photons presumably only interact with the phonons by interacting with the medium the phonons are a part of (phonons aren’t a fundamental particle, but a quasiparticle, a collective behavior of a medium which acts in many ways like a particle), and I doubt this would work in normal atmosphere?
HOWEVER: there are some cool things that can be done with optics, and apparently it is possible to make some light be focused in a way such that a screen appears to float freely in space, without an enclosure, at least visible from a fairly narrow viewing angle.
Perhaps an extension of this could allow for what you are hoping for.

Do phonons have quantum properties?
Yes! That’s actually kind of why they act like particles at all, rather than just “there’s some vibration”.
Nifty topic today! Love your channel, thank you. ❤
My neighbors think I have a laser made of sound LOL
Most importantly, we can find out whether unheared trees make sounds.
We already know the answer to "If a tree falls in the forest in a vacuum..."
There are recent studies showing that vascular plants ( which includes trees) emit sounds caused mainly by changes in volume of fluids and gases at the cellular level.
Ah yes real applied physics, not like those khm khm string theorists
"Researchers at MIT have developed a technique that uses lasers to transmit audio messages directly to a person’s ear. This method leverages the photoacoustic effect, where a material emits sound waves after absorbing light. Essentially, you can project your voice or other sounds to a specific target without others hearing it. This technology could be used for private communications, targeted advertising, or even in noisy environments where traditional audio methods might fail. It’s quite an exciting development!"

@@treelineresearch3387 will listen to that. Thanks.
Wha?????
Sound quanta?
Wasn't sound just a kinetic phenomenon?
If it really is a quanta, then what's stopping it from propagating in a vacuum?
"There isn't anything similar for sound"... Yes there is... It's called explosives that are sensitive to pressure disturbances. If you build a resonating cavity out of such a substance you will get a sound sasen for a brief second. That's essentially what shaped charges are...
We probably had this twenty years ago, but it was buried by the military and other complexes. It's called "long-range acoustic device" They were focusing sound by creating 'flat' emissions of ultrasonic frequencies. When arranged in a tube shape, it would form a waveguide for sound in the middle, blasting whoever you pointed it at. I'm 100% certain the waveguide producers could've been developed into a sound-laser, but helping people? feh
3:58 "They did this experiment in vacuum" - that sounds like the killer caveat right there. A quartz crystal oscillator has an extremely narrow resonance band, but you can't get any significant power out of it. Read the Wikipedia article on "Q factor" (no, not Star Trek!). I''m not seeing any amplification of power here (or rather, the transformation of input power from one form to a highly tuned/focused output power). Another analogy would be exciting a pendulum, and claiming my grandfather clock is a "mechanical laser".
Misspelled sonic disruptor
😅The sound engineer in me got angry when you mentioned that humans can't hear 20k and above. Settled down quickly though as I realize that that is a generalization. Most people can't hear 20K . Part of my training process was to be able to identify discrete ranges of frequency based on their effect on my preception of the sound. 20K was very much part of that study. I used to be able to actually hear 20K (23K actual) but as I have aged my able to "hear" these frequencies has been lost ...around 16-18K now... but I can still precieve them by their effect on certain complex waves. Example: A flute recording with less 20K in the spectrum would sound duller than one with 20K .... even if I can't hear the 20K itself.
Nice story
I was thinking that you must had been young.
last time I tested with very high end equipment that could produce it, and I could hear up to 28k. I agree, without a lot of these higher frequencies causing effects in the audio, much depth is lost.
@@namm0x326the same as the dude above, you must be a teen or younger if you are able to hear above 18khz.
If you are above 20 yrs old, it is physiologically improbable.
Above 30 yrs old, it is impossible.
Either you are genetically special, but you are an extreme statistical outlier.
@@namm0x326most likely, it is placebo effect.
Can ultrasound tell us if a potato is cooked without having to try to push a knife through it?
Not sure but it could probably cook the potato 😆
I think that's the primary application.
i luv your podcasts Sabine !!!
Why not just use an AC voltage on a piezoelectric actuator? This would also lead to coherent oscillations, with the spectrum being given by the clock precision in the AC source.
I'm favoured financially with Bitcoin ETFs approval, Thank you buddy.$28,600 weekly profit regardless of how bad it gets on the economy.
Very interesting. It could also be useful in medicine, e. g. to remove kidney stones with "surgical" 😊 precision!
Hmmm could we implement a MEMs based version of this with integrated photonics? This is Matt Eichenfield's dream!
Hey, what do you think about the syntergic theory by Dr. Jacobo Grinberg?
The thing with the phonons sounds like you can make air currents visible. You sent sound through air, the turbulence in the air affects the speed and direction of the sound, and if you can get sound to influence light in a precise manner like you described towards the end of the video, then theoretically you could make air currents visible. Very, very theoretically. I mean, wouldn’t it be cool to see wind and turbulence in the air the same way we see waves or turbulence in water?
Neat experiment and nice explanation. One nit-pick: phonon-light interaction is hardly new and doesn’t merit ‘recently attracted attention’…
Heat is the variable. It can accumulate or dispersion into atmospheres at variable velocity. In mass, it tends to be constant until it is renewable heat energy is disrupted. Outgoing heat energy singularities outside of mass faster than incoming renewable heat energy is slow decay of mass. Aging.
So I checked to see if my player playback speed had been slowed, but nope, Sabine apparently has been directed to speak more slowly! I've noticed in the past couple of vids.
Sonic screw driver
I believe you can already do with a laser diode conceited to mini sound amplifier and the laser is pointed at a solar panel connected to a speaker also Hacking into an Amazon Echo Using Laser Light and also sound at long distance like listing in on a home by pointing a laser at the windows and pickup the vibrations . and also how gpu chips are made like in cartography in chip manufacturing very deep trade secrets lol.
Great work by these scientists! Great discoveries and uses for this tech lie ahead, some of which, I suspect will not be made public!!
I don't know what to make of this. Form reading the comments this is either obvious and old or so incredibly new that it is a game changer.
… it this similar to the ultrasonic surgery done in China? The patient is immersed into a sterile bath, n the ultrasonic surgery procedure is done in the bath.
Your channel is a real treasure trove of inspiration. Thank you for your contribution!❤️😁🏏
Firstly hear sound leaser exist.
LASER.
These technology updates and news are amazing. We all live in a yellow submarine...Thank you.🌺
The Mayan warrior brought the most expensive laser in the world (according to them) and it was super cool. The light went up all the way to like the stratosphere
There were other super expensive lasers bouncing around the surrounding mountains, but that beam was crazy
Nice topic. Good length too. Very digestible and I feel smarter!
Thank you for the video.
Seen, sound tech used to make pizza on video. Would like tocknow how they taste.
Light Amplification by the Stimulated Emission of Radiation = LASER,
Is that how the ancients used giant middle school recorders to move giant stone blocks?
I guess the first applications will be new weapons. For example, new sound guns against pirate ships.
Sadly, that's true for almost any new technology - if it can be weaponized, it will be before long.
You mean like the LRAD? A phased array of sound emitters to keep a narrow beam.
Very interesting! Thanks for speaking about this topic.
Wow talk about Firing Up My Speakers!
my neighbors should buy me these sound-laser loudspeakers :3
David Lynch's Dune sonic weapons come to mind :(
Thanks!
Thanks in return!
Masers was with microwaves, so I think that sound could work
Thank you again, Sabine!
Now this is interesting! Better holograma for big tech glasses?
I don't understand any of that but I appreciate the effort on your side😅
Sound by definition has to travel through a medium and be heard. I’m waiting to hear the perfect picture sound laser based piano.
Hello, Sabine. Could you make a follow up for these hype videos? There were a lot of topics covered here in the past, but it would be nice to revisit e.g. 1-year-old videos about promising technologies/theories and review their progress.
I think 2 or 3 years would be more appropriate? Things take time.
Phasers are not lasers
Lasers are cool! 🤙
I always found it funny that LASER references both Light and Radiation... Aren't they the same in this context?
Because 1. the first demonstration of the principle was the MASER, i.e. Micro-wave Amplif.... and 2. the Radiation in xSER signifies the process, not the product of the process.
Wait, so the laser suspends the ball and set it ringing. The electric field interacts with the ball and the output is very spikey amplified high-energy EM waves corresponding to the overtones of the sound? No complex materials chemistry and orbital calculations?
Oh wait the whole process has to start with laser inertial confinement.... oh, I see, this is just what fusion people do with lasers for fun!
At first I thought these were going to be sonic-disruptors, with some medium that projects "coherent sound waves". Which doesn't make sense, because in a wave of waving "stuff", the energy is proportional to the amplitude, but with EM radiation, the energy is proportional to the frequency. So more and more coherent waves would mean bigger and bigger peaks and troughs in the pressure conducting medium, not focused collection of self-similar rays like a proper laser.... Oh well, so much for sonic disruptors.
Dumb laser question: are the photons in a laser beam entangled? why or why not?
Yes, exactly.
No, the photons in laser beams are normally not entangled. They are coherent. However, lasers are often used to create entangled photon, typically by shooting with the laser at a non-linear optical crystal. That converts one photon into two entangled photons of half the energy, basically.
Perhaps this can be used for fusion.
@@trucid2
There was a controversial attempt to produce fusion with sound called sonoluminescence/sonofusion/bubble fusion.
The process of sonoluminescence is fascinating, and this new sphere laser transducer could potentially improve the output.
The temperature required for hot fusion is 45k degrees. The acoustically trapped bubble in these earlier experiments can reach 20k degrees, or close to the surface temperature of the sun.

So, disrupter type weapons on the horizon?
I came here for the science. Stay here for the jokes!
i vote we call this a Sonic Laser because it sounds cool
First time I've heard of a phonon 🎧
Phonons coupled with Photon is decade old. Molecular Lazer.
Prismatic Molecular Lazer.
Inject that into dynamic polygon with EM polymer gas and make propulsion system that'll be like ah "Bat Outta Hell." 😮
Wish NASA hurry up. pppffff
Sounds good.
Thank you
Never knew that laser is an acronym!
never heard of phonons
Did you hear about sound in the vacuum?
The reason is that they don't exist.
Phonons are a quasiparticle, a particle-like collective behavior of a material/medium .
Observed when you closely examine vibrations in very very cold materials.
@@drdca8263 How the particles looks like? How many are out there?
@@ShonMardani What do you mean by “What do they look like?”?
Phonons aren’t macroscopic. They are quanta in the collective behavior of a material.
Regarding how many particles there are, do you mean “How many types of fundamental particles are there?” or “How many phonons are there in a material?”? For the former question: phonons aren’t a type of fundamental particle, they are quasiparticles, a collective behavior of a medium that acts like a particle.
If you are asking how many types of particles including quasiparticles there are, uh… I’m not sure if that’s a question with a well-defined answer?
I don’t know if there’s always a clear distinction between whether two quasiparticles are or aren’t of the same type. Like, is a phonon in a diamond the same type of quasiparticle as a phonon in some pure iron? If not, what about in different grades of steel? Or like, for different magnetic field strengths, the quasiparticles for the fractional quantum Hall effect have different statistics I think, so should they count as different types?
If you are asking how many phonons are in some material: I’m pretty sure that unless the material is very cold, the answer is “very many”.
That Florida beachfront property joke may have been a little bit too soon. Dozens of people died.
she made this before the catastrophe
But it will not be a laser but rather saser (Sound Amplification by Stimulated Emission of Radiation).
Or _PHonon_ Amplification...
Someone needs to start working on Phasers now
