"Eterbium"? The name of the rare earth element is Erbium!

Great video

Excellent Presentation. Thanks. CPU's can be made round with glassfibercables perhaps and a lasergun or ledgun at the beginningpoint.

Hey I recognize this voice!

Well-Done

Excellent Presentation. I watched first hand the development of a Fiber Laser used in LIDAR Applications from the perspective of a PCB Layout Engineer dealing with Pump Diodes and Optical Racetracks and the electronics driving them. Made for some interesting challenges. I never expected to have to change a board layout because of the reflectivity of objects such as a Stop Sign at the frequency of our Laser. Now I have a much better appreciation for the issues facing the scientists and the problems we Engineers had to solve to create a low cost mass manufacturable device. Thanks! We succeeded by the way.

400 nm is NOT blue. It's violet. It's absolutely pathetic how many science communicators get that wrong. The visible spectrum ends in violet, not blue. Also, it's MI-cro-ME-ters, not my-CROM-i-ters. The way you mispronounce the word, it means an instrument for measuring small distances, not a unit of length.

👍!

Amazing, to think you can now buy a home use Fiber Laser

What is unpumped self-lazing @6:48?

I can only understand half of the video......

Excellent and detailed explanation. The issue that I am involved in is looking for the best temperature for the best wavelength so that the pump diodes bring the least pressure. The challenge is the temperature of the pumps and the temperature of the oxygen and nitrogen during cutting. By bringing the pump temperature to minus 12 degrees, we obtained lower quality and energy

Thanks for amazing explain

Nice

If anyone can tell me where I can find that music by itself 💀

Okay but can we talk about how good the music in the beginning was holy shit

head explodes

Both clear and very informative. This was useful!

wow i didnt know all this was leading to engraving and other streams of art and income. thanx. i was really hoping you could recommend a portable unit for rust and paint removal on cars as rust repair is the most time and money consuming. seen a portable unit by Questt

Good physics love you from India Punjab Amritsar

I work with two 4,000 watt, and didn’t know what was going on inside. This video helps out. They are fiber lasers. I’m always amazed of what you can cut.

This video was done terribly, too much hype, couldn't stand to watch it much.

good illustration

Thanks for informative Quality content.

You gave an excellent description.We learned a lot about fiber lasers. 👍💐

It's an easy explanation to follow if you replace all the formally unknown words with "things" and "stuff" and glaze over the other information he may have given.

awesome high quality material

1:18 the light spectrum table is backwards. gamma ray is long wave and radio is short

Loved it.

can you refer some book to understand fiber laser from scratch?It will be very helpful for me then.

hello sir who is watching from IIT Bombay?

Innovations leading to Very high quality fibers and fiber components from Nufern.

Excellent presentation

matching ultra high price :D lol

This skipped way too much in the beginning so that you are lost through the rest.

🤯

Holy hell, amazing explanation.

This feels like one of those poorly done videos I used to watch back in 8th grade science class.

This is the perfect kind of summary that should be done before most of engineering (and other fields) courses, and after this, the detailed explanations would make sense for the first time.

WOW. ALL THAT TO MAKE MY LASER POINTER WORK.

If you slow down your exsplaination too about half speed I might be able too keep up. Its evident you know We the viewer are not at your intellect level from your introduction. So if you want too encourage us, the intrested viewer, dont speed rush us with your many years of collected knowledge in a few minutes of vidieo. Slow down, do many short lesson vidieos. You werent born with it, and you werent fed the knowledge in one heaping spoonful

It’s big brain time

Fantastic video and explanations. Thank you , even years after you made it, still very helpful. WTG!

Informative video but the flickery green ball was very distracting

that may as well have been in chinese

Excellent information. I was a little worried with it started with an animated photon, but I'm impressed that the core information was not simplified beyond reason. Of course, I'm a guy who has Bragg's Law tattooed on my arm.

This is much higher quality than I expected

This green monster with long hands is really scary
