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.

[@rogerwebb9600]

You are very welcome

I'm a postman and I've never heard or even thought of such a simple yet complete way of explaining the operation of a fibre laser to a layman as you have done. Genius (without the o)

[@leonardveranojr5300]

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

[@rogerwebb9600]

I appreciate that!

[@programorprogrammed]

What a wonderful combination of complexity and simplicity in its design

[@malakiblunt]

After watching styropyros fiber laser vid, to see what they can do 😱Came here to find out how they work

[@NRiggiKnives]

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

[@Samuelir96]

I thought my local cockatoos had come to visit but it was in the video

[@itamar8424]

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

[@fabiocamo]

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.

[@bicates]

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

[@dii1231]

I would buy at TOPTICA! Other than that, great video!

[@svocklit700]

Do the fiber laser in sink and how can you tell they fire in sink? What happens if the fiber laser didn’t make pulses and was just emitting power? would the heat of the laser increase.

[@petevenuti7355]

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

[@qss6609]

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?

[@mackenzieb-eu3mf]

I would also be keen to learn the answer to this question as well

[@NotJustCreative]

So, basically, it works like multiple people shooting bb almost at the same time at the same target delivering equivalent output similar to a single shotgun firing a birdshot. That's what my brain got out of this. Does this apply to fiber lasers that can cut metal too?

[@varinaboy19]

Trumpf lasers best of the best

[@multiforc271]

hi, ty for the video. i have a very elementary question, optic is not my main field: how to introduce a series of laser beams into a single fiber optic ?

[@lazaryanya9407]

They use special fiber optic junctions that can introduce laser light from 3 sources into one optic cable. However not all of the laser light is in the middle core fiber. The loop or amplifier section moves all the laser light into the middle core fiber. You never get more power out than what you are putting in. The explanation is lacking in that regard.

[@zohirlon6059]

sir i have question is possible to run 50w fiber laser source with co2 laser controller such as ruida for exmple ? thank you sir

[@rogerwebb9600]

Sorry no

[@xiaotianchen9912]

Is it a CW laser? But why the laser diodes were switch on and off?

[@omsingharjit]

So this is similar to q switching in fiber right ! But what caused in fiber to q swich ? And in case of co2 laser this q switching process should be different right?

[@rogerwebb9600]

Totally different

[@othoapproto9603]

Thanks, I think the word you were looking for is Pulse.

[@rogerwebb9600]

Yes! Thank you!

[@othoapproto9603]

@@rogerwebb9600 Again, thanks for the wonderful video. Was wondering how they worked. I understand elector magnetic coils and capacitors. Didn't know a photon could be stored up as a charge.

[@jacobsvickers3945]

I have a background in physics and it's been awhile since I have played with the mathematics but I'm trying to combine diode lasers to melt and or weld steel wire. This is for purposes of additive manufacturing. Are fiber lasers practical for this application?

[@rogerwebb9600]

Yes I think a fiber laser will do this

[@moloysarkar1725]

Yes they are, we're already doing that work in our lab here in India.

[@jacobsvickers3945]

That's all well and good but will it generate the needed 1.21 gigawatts?

[@Yngvarr77]

you need multiple lasers for that

[@AusWorkshop]

@@Yngvarr77 Yes, and a flux capacitor I think. 😃

Have any Fusion researchers upgraded to fiber laser? Will the National Ignition Facility upgrade to fiber?

Judging by the Russian R&D and production centre they are are doing well.

Soooo how i turn my 30w fiber into a 24kw???????

[@zaddle6883]

cascade more lasers and do optical loop

[@Didisixty]

First of all you have to understand the difference of pulse power and average power. A Fiberlaser is a Pulslaser. 24kW is the Pulse Power of 1 Pulse. 30W is the average performance. If you have a Pulse power of 24kW for a few Nanoseconds and a break for 500u Seconds to the next Pulse that means it is a average power of 30 Watts.

[@kland15]

I have a 50 watt laser. So is the math 30-24=6 so 50-6=44. Is my laser 44kw? 0:01

[@rogerwebb9600]

Hi, it's not quite that linear, it is verry complex but the fiber itself is an accumulator of photon energy similar to a capacitor (impulse battery) it charges up over time and then discharges very quickly. this all happens in a timescale of billionths of seconds.

[@kland15]

@@rogerwebb9600 ok, thank you.

[@kland15]

@@rogerwebb9600 could you please tell me what a seed laser does? I’m guessing that it’s fired directly into the fibers core just enough to excite the other photons to attach to it to get out.
