light amplification by stimulated emission of radiation, not via stimulated…
Lasers came from UFO crash retrievals
Keeping our feline overlords entertained is absolutely the most important use for the laser. 😂👌
My cat used to love chasing the red bug.
I've been in love with lasers since I was little and recently got my hands on a 10 Watt diode laser. It's been incredibly fun to see in action. It's amazing how powerful compact lasers have become in recent history.
I too recently got one. I've been having all kinds of fun with woods, plastics, metals, clothing, etc.
@@Hunting4knowledge Right? It's very fun
Look up styropyro to see how powerful handheld lasers can really get
The sharks have freaking laser beams on their head
Every animal deserves a hot meal!
might have to settle for sea bass
@@NorthOntarianAre they ill-tempered?
Their freaking heads*
my cycloptic friend says absolutely@@the_once-and-future_king.
Great video once again, and on that last note: RUclips channel 'Hacksmith Industries' has been working on actual lightsabers for a while. Three years ago their development completed the proto-saber stage. This means they have a working lightsaber, but it is powered by an external source. They are currently working on getting the power source inside the saber. My estimation, based on their latest update, is that within 10 years we will have lightsabers (if all goes well).
Thank you for the info! I'm gonna go check it out now. 👍🏻
Ill have to go look at that. Thanks. But without the Force, I always picture the meeting between Indiana Jones and the fellow with the swords in the Marketplace when he's looking for Marion. Sword Guy: lots of fancy moves > Indy: gunshot.
@@kitefan1 What they made is more a plasma saber, so it won't deflect bullets, but it might melt them😉
@@Panthror LOL. Probably illegal in Calif then. One of their biggest markets.
@@Panthror Very scary.
I've only ever heard lasers explained once before, in a manner that I understood it immediately. That was about thirty years ago. Good job!
50 years ago researchers from Bell Labs gave us a demonstration of lasers in school. I grew up next door to the Labs. Two of the guys from there that invented the transistor were living in my home town when they did that. We were basically their community. Even I've worked on the campus.
When lasers were first produced in the 1950’s and 1960’s they were called a solution looking for a problem. Amazing how important and widespread they have become over the years.
Even by the 1970s no one had still come up with a single practical use for lasers. But that didn't lesson the excitement about them. Scientists from Bell Labs gave my grammar school a demonstration of them way back then. How excited they all were was obvious.
Ironically "They were called a solution looking for a problem" is true when attached to military weapon targeting systems... quite literally.
There were no lasers in the 1950s.
First one was invented in 1960 at bell labs.
@@Annihilator2011 Bell Labs didn't invent the laser. They were only early experimenters with the technology. They tried to invent something to do with lasers. Even by the 70s they has still drawn a blank on that note too.
@@1pcfredOkay, it was at Hughes Labs not Bell but the point being there were no lasers in the 1950s...
14:31 Haven't you heard of the Hacksmith? He's working on improving his lightsaber prototypes, of which he has many.
“Stimulated Emission” will never not be funny
"AMBATUKAM!!!"
- laser
Lasers make great special effects at rock concerts! I first saw this at a Blue Oyster Cult show at Moody Colesseum in Dallas, Texas back in 1975.
I’m just as curious about the person who invented laser eye surgery. Not sure how you could look into a laser and think that it might actually be useful to help people vision from the experience before we knew about it
What corrective vision eye surgery does is cut the cornea in such a way that it reshape the curvature. Human hands can do it pretty good but computerized lasers can do it stupidly good.
Your comment was going quite well until it collapsed into gibberish at the end.
Gotta love Val Kilmer movie quotes....
"it came to me. It is possible to synthesize excited bromide in an argon matrix. Yes, it's an excimer frozen in its excited state."
Bodie : "Th... That's impossible."
Chris Knight : "It's a chemical laser but in solid, not gaseous, form. Put simply, in deference to you, Kent, it's like lasing a stick of dynamite. As soon as we apply a field, we couple to a state that is radiatively coupled to the ground state. I figure we can extract at least ten to the twenty-first photons per cubic centimeter which will give one kilojoule per cubic centimeter at 600 nanometers, or, one megajoule per liter."
Thanks for this, now I know how Laser Cats were created, not by one person but by many...
I always think of the movie "Real Genius" when I think about making lasers.
I'll never forget the presentation Bell Labs scientists gave my school. People in this video were on stage in front of me. Because I just happened to be in the right place at the right time.
Well, we do need a working weapon by mid-May.

I for one accept our Feline Laser Overlords
I don't trust any feline ever.
Excellent beginner explanation! Now take it to next level, coherency
Don't forget laser communication via satellite. The Deep Space Optical Communication (DSOC) mission recently launched with the Psyche mission.
I believe NASA actually tested this last month and it worked perfectly. They fired a near infrared laser signal encoded with test data including a HD video of cat belonging to one of the mission scientists(yup, the first deep space laser communication signal was a cat video, because of course it was) back at earth from over 10 lunar distances away.
The laser signal was recieved by a ground station telescope in Australia and then relayed to the mission controllers at NASA's Jet Propulsion Labs in the US. The signal took longer to travel across the globe from Australia to the US than it did to travel from almost 10million miles away in space.
Referring to a (possibly apocryphal) story I read 30 years ago, so forgive me if it isn't perfect. While set to receive some award for their work, Maiman presented his wife with a ring made from one of the rubies he'd used making the early lasers. Ms. Townes looks to her husband and asked why he did not do something similar, to which he quipped, "Because the crystal I used was made of cyanide."
Great job
Thanks Simon
After all the stimulated emissions in this video, I need a cigarette!
Wow, I was pleasantly surprised by how accurately the physics was described.
I know my electrons get excited and release energy into the play button whenever I see a Whistlerverse notification.
Lol
Simon’s dressed down appearance is surprising
Am I the only 40-something who wants to fall over, cackling, every time he says ‘stimulated emissions’?
No?
Only me?
thanks you
GEORGE SANTOS!!!
What does he have to do with this video?
GG ALLIN
@@Sniperboy5551 He invented lasers!
@@cranklabexplosion-labcentr8245 Ah, yes, the REAL Jesus Christ. Back in the 90s I saw a VHS of him performing. He threw his own sh*t into the audience. I think he might have penetrated himself with something too.
You know, he claims to be Jewish so space lasers. (Lying a-hole)
Good argument for Einstein coming up with the formula in the 20s as well.
You'd need to be more specific really.
Watching this while cutting Baltic plywood on my big ass home brew laser cutter.... 130 watts of C02 laser in my workshop.
Simon wearing a polyester under layer with a stretched collar is throwing me off.
In the early 1970s geeks from Bell Labs gave my classmates and I a demonstration of lasers at school. It was bizarre. I suspect today they were using us as a practice audience for their presentation. Because they were not good at being on stage. So I've probably seen some folks in this video in real life. The Labs were early pioneers in work with lasers. We were a grammar school. So really young children. They did say the laser was a solution looking for a problem then. At that point it'd done nothing of practical value yet. But they were all so excited about it.
Lasers...Helping sharks everywhere achieve their full potential.
Nothing about sharks with lasers on their head aww
or a laser guided bee cannon
I knew this had to be a Gilles episode :)
Light sabres in the future? I thought they were from a long time ago, in a galaxy far, far away.
Amazing Video Like Always !!! ... i just love adding new mostly useless knowledge to my Brain !!! ... lol #Fact´s
Do an episode on the Grover shoe fire disaster of 1905.
NASA is working on a laser to melt lunar dust into a molten gell that can be squirted on a 3d printer to make a building as strong as concrete so it will be the fundimental method to build habitable buildings on the moon.
Not sure the conclusion follows from the premise.
@@eadweard. there is a 60 minutes program about 3D printed buildings mentioning NASA planning to use it for lunar habitations.
@@davey7452 Right. But that doesn't mean it _will_ be used for lunar habitations.
I would give Maiman the credit for inventing the laser though he didn't create the theory behind it.
Hacksmith is working on the lightsaber. Don't you worry.
And here i thought they were reverse engineered from the alien craft that crashed in Roswell 😂
Are we still doing phrasing?
"Stimulated Emissions"
now all we need to do is find a shark to attach the freakin laser to.. sea bass may have to do
They already have trained dolphins equipped with poison dart guns... allegedly. There was that thing a few years ago where supposedly some of them escaped to the open ocean after a hurricane(Katrina?) flooded a naval training facility on the coast, or so the story went.
I seem to recall seeing a video of a Beluga whale spotted by some Swedish fishermen up in the Baltic Sea, that had been custom fitted with some sort of special harness(potentially capable of having cameras/microphones or other devices attached to it, believed to have been made in Russia.
4:04 science today
How is it that this site has over 3M subs and The Casual Criminalist only has 534K subs? chop, chop Simon!
Surely light sabres were in the past?
There was those silent ones that perfected this tech to assemble a space station, not that it matters these days more that the cheesecutter.
wonder how many of their friends they "accidentally" blinded showing off their new invention.
hey hold my beer and watch this.
Love your content!❤❤❤❤
Oh fact Boi, you would rejoice to know that we're super close to lightsabers in all actuality lol
Not going to name the channel but a quick RUclips search would show any interested persons to a pretty cool work in progress 😎
Ok, so I've watched damn near quad digits of Simon's videos....why is he not dapper today? Is that a pajama shirt?
It's a little better with the breaks you do between ideas; more time to sink in.
"Easily built in the megawatt range"..... Kw, maybe can be described as easy, but certainly not megawatt range lasers. Even if it is a co2 laser
Britain - the answer is always, 'a Brit', we invented candles, oil lamps, gas lamps and the lightbulb so it goes without saying that we invented the laser. History is essy when you're British - we invented everything.
It's great to see you ❤❤
They don’t give Nobel prizes for theoretical physics, and gravity is technically just a theory. Re: einsteins prize
Like germ theory?
Sod the lightsaber, I’m not a Jedi. Just give me my hoverboard already!
Speak for yourself.
@@Obi-J I was. I’ve no interest in owning weaponry.
Ok they are all the same frequency and phase, why doesn't laser light diffuse, I mean spread out or diffract ? I know lasers can be very dangerous, if it goes in your eyes and is focused on the retina, the power could be thousands of times greater. You have to have glasses that will filter the right wavelength of your laser. They cost a lot of money, and if the laser shines directly into them, they don't hold out for ever. a couple of minutes maybe. I mean for powerful lasers like medical ones that are class III. Your CD is class one I think. Class IV is the strongest, military ones.
The best invention for cats and their slaves of all time
"stimulated" "pumping mechanism"
We.... are still talking lasers, right?
Ali Javan received the Albert Einstein World Award of Science in 1993.
There is also the SPIE Maiman Laser Award, Arthur L. Schawlow Prize in Laser Science, and for about 11 years the Einstein Prize for Laser Science
Hacksmith would like to show you something bout the ending
Hehe, "Stimulated Emission".
Yes, I am that immature 😔
I'm not sure there is anything you can't do with a Laser
I have stimulated emissions quite often.
Perhaps I could shoot laser beams outta my, uh, um 😶.....
optical engineer here 🙋🏻♀️ I build directed energy weapons so I literally work with lasers every day. if you want a little more info on how lasers actually work, I also have a video on my channel going into some more detail on that topic 🙇🏻♀️
Simon, a light Saber isn't really a laser beam but a focused beam of PLASMA. That's just a bonus fact for you. Here's another, some RUclipsrs have managed to build a working model, though limited since it isn't portable and classified as an Arc Cutter.
I very much enjoy your content, but the flashy border lighting is super irritating.
"La-ser""
Real Genius duh
❤❤❤❤❤❤❤
thebluuuuuuuuuuuu but howboot uuuuuuhh
The end made me chuckle, cause didn't fact boi cover lightsabers on his Science Unbound channel?
Really? No clips from Real genius?
Keeping our feline overlords amused had me laughing
WTF .... 15 mins on lasers & not one mention of Dr Evil or shark-mounted laser beams ???? . lol
If it's any consolation, the original thumbnails didn't say "inventing awesome" but rather "Frickin Laser Beams"
@@TodayIFoundOut .. all good then
I was taught it was "Light Amplification by Stimulation of Electron Radiation", the dumbed down version only seems to have come into existence in the last few decades.
You have the dumbed down version.
@@joeds3775 Good job Skippy
Aliens.
6th?
you speak too quickly
Who invented glass?
Glass is a naturally occurring material. It’s literally just melted sand. As for humans using it. That predates written history
Nature, nature invented glass
@@biiill5259 making glass is actually a bit more involved than simply melting sand. Silica is about 72% of glass we produce.
@@captainspaulding5963 volcanic glass is produced naturally. But that's not the kind of glass we use today.
The sun is a deadly laser
Nope.a laser emits only 1 frequency ( colour). The sun emits on all frequencies.
@@joeds3775 r/woosh
First. Where is my medal?
Here
🤘🏻🤘🏻🎸🎸
the aliens invented the laser i refuse to believe humans invented such a marvel of technology
Does the name depend on the frequency? Visible light: laser
Microwaves: maser
Infrared: iraser?
Gamma: gaser? (lmao gay laser)
you speak too fast. do you have a train to catch or somewhere you must be in a hurry? I solved this problem by going to youtube settings and changing playback speed to .75. Not only is much easier to follow but there's just enough change to make you sound a little funny. Like you're just drunk enough to try to not sound drunk.
Simon knows the attention span of his audience
Of course Germans.
First to comment lol. 😁
nope. the other guys beat you by one second. you are THIRD hahahaha
No I'm first
How they work? Pew Pew!
Done!
I now await Simon's follow up video, explaining who first created the "stun" setting! 😁
Aww. Those are phasers. It's a common mistake, though, so don't feel bad. 😅
@@trevorwilliams6362 It's not a mistake, I do know the difference, but ignored it to emply what Earth people call "humour" 😁 For precedent I refer the jury to the Bing Bang Theory mining a similar theme when they were using laser measuring equipment directed at the Moon, and the visiting jock worries this means they will blow it up, so they assure him it is set to stun power
@joegordon5117 I'm sorry my retort didn't have any canned laughter attached 😔
Simon, I know how much it pained to you suggest the scientists should develop a working lightsaber, but its really would be novel. Probably more practical in a smaller format, such as surgical scalpels or cutlery, but who wouldn't want to see a real one?
If LASER printers and barcode scanners supposedly came out in the early 70s, then why didn't we see them in use until the mid-to-late 80s?
I wouldn't have expected Simon to know that lightsaber blades are made of plasma contained within an energy field, but I would expect his writers to know better.
This isn’t even Simon’s channel. But yes the writers should have looked into that a tad harder considering their viewer base
There is a clip of George himself calling them "laser swords" they are lasers. Wonky Scifi lasers, bit still, lasers.
14:27 Are you mad, sir? We'd be living long ago in a galaxy far, far away!
All hail the feline overlords!
My favorite use of the laser is the interferometer - it can detect vibrations as small as the diameter of a hydrogen atom! incredible stuff.
You have the ability to blow up planets sympathetic to the rebellion, but you want to play with vibrating hydrogen atoms instead?
I love this project. Places keep them coming ☺️
"Invented the first gas LASER..."
* "Invented _the_ gas LASER." Others after that were just developments. The first one is _the_ (one) invention.
