One question always sticks with me. How does the coupleMirror work exactly. Is it 1, it reflects some and couples some out or is it 2. It is like opaque until the radiation is strong enough and only then gets more or less transparent for the beam, like a Q-switch ?
Yeah; from what I've read, (I'm a layman so, I'm not an expert,) one of the (two) mirrors is partially coated so, when the amplification reaches a certain point, the light bursts past the coating. I think that's why the old lasers like this were "pulse" (?)
I think it uses statistics. The most advanced mirrors produced by 3M use a series of reflective layers. Each layer has 50% chance of reflection, and 50% chance of light passing through. One side of the laser gets 10 of these layers which gives a chance of 1/1024 for the light to pass through, and the other side gets many more layers which gives a probability of almost 0 for the light to pass through. Hence we have 1 mirror that is 100% reflective, and the other which is 99.9% reflective
Thanks 4 your answers after so long anyway 🤠🙌. This always sticks with me. Also because I red, that for CO2 you can basically use a 100% Mirror with a small hole in the middle to couple out some of the radiation (you can run some Lasers athmosperic, or cover the hole with a thin transmission window) But this leads me to think like "ok, but then I have broken my resonator in exactly the spot it is most relevant to the function" 😅 However, I guess I just not yet fully understand everything about it and the physics is not that simple as "light goes bouncy between two mirrors, hence laser" Time to get me a better book on it 😓
There's something about a lot of 'scientists' that they think putting many French or Latin loanwords in their explanation will make them sound smart. In reality your explanation will simply fall on deaf ears to anyone but the people that already understand the concept. So no, you don't sound smart, just elitist.
Yeah; especially Botanists! What's with all those "elitist" Latin names!? And, those Chemists, with all that "hydro- oxy carbo-" stuff! Is that French? Worst is the Mathematicians and Physicists with all those squiggly, elitist, doodles they put up on the boards!! What's wrong with normal numbers like the rest of us use!? Is that Russian writing? Are they "Commies"!? 😆😅🤣🤡🧠=💩
It seems like a crime that Theodore Maiman didn't get a Nobel prize! Was he at least given one posthumously?
Alfred Nobel's will forbids posthumous awards.
So, in essence a laser is a "photon copier" and because photons are bosons they can occupy the same space which makes it a laser?
Do you have a link for the full presentation of the laser? The clip used at the start of the video. Thanks
yes
@@dcgeeked8917 could you share it please
@@azoth5420 did you find it?
@@owenwaldo unfortunately no
This isn't the same but, the inventor's wife. Pretty cool. ruclips.net/video/Ulg_SP7HDXw/видео.html
How powerful was Maiman's laser in Milliwatts ? My strongest laser pointer 450nm has 5 watts 💙

Awesome
Its surprisingly small considering most new tech back then took up either rooms or was not pocket-sized😂
Mr beast made a Lazer maze because of this

LOL! And you sound dumb and lazy.
