How a Fiber Laser works & how a 30w fiber laser can output 24kw of laser power

I´m physicist and work with laser since 1983. Dear Roger, I have never heard or even thought of such a simple yet complete way of explaining the operation of a fiber laser to a layman as you have done. Genious.

You can always tell when someone knows what they are talking about by the simplistic analogies the use to explain something other people don't know. You are a master of your field. You made it very interesting and understandable. Thanks Len V

What a wonderful combination of complexity and simplicity in its design

thank you for that explanation ...

Thanks for the video

Thank you Roger, Roger

Excellent explanation! As an older person I just wish that the beginning still images were larger so I could see them better.

Nice class, thanks for sharing

Teacher, thanks for the explanation! we have an IPG laser source here.. God Blessed You

Pure genius

Excellent explanation, always wondered how fiber lasers worked...

It's very helpful, Thanks.

Helpful videos, been trying to dial in titanium color settings on a 20 watt fiber. Green has been elusive!

Tks sr.

Thank you

Thanks for this excellent explainer... out of interest, does the Dragon weapon grade laser, work on a similar principle?

Thats cool such a great explanation I have a few questions though how does a fiber laser increases its power is it by adding more diodes or using diodes with higher second completely theoretical if I want to make a very powerful fiber laser can I use c02 tubes instead of diodes or would having to wait for the chemical reaction in the tube take too long

Great tutorial, thank you! I have a question. There are numerous pumping laser diodes to produce rated output power. If pumping diode fails, I presume the output power will be reduced. Is there a way to test all pumping laser diodes functioning correctly? Does the fiber laser manufacture, like Raycus, provide the functional diagnostic tests?

Congratulations for the explanation, very good! But I still have a doubt, I want to buy a 1500W portable laser machine, its power consumption says it is 4.8Kw/h, input power is 220V... I need to use a power stabilizer to avoid fluctuations in the power grid wherever I go to work, but because of that peak power I'm in doubt now, will the machine power supply have this peak power of 24KW? Or in the power supply (energy input) will not have this peak? Thanks in advance for the tips.

Insightful , I learned something new, but, also seems overly simplified for someone who knows a little bit.. So is the control laser basically what gets amplified, and the fiber itself the lasing medium with the diode lasers as energy pumps? And if so why doesn't it spontaneously emit? Or Is it more like a q-switch, where all the energy of the diode lasers get stored in the fiber and the control laser operates a q-switch to let it out? And if that is the case how do you keep them phase matched? The way you described it , I could interpret it either way. Also, how long is that fiber? Thanks
