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
4 ай бұрын
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.

Thank you Roger for your video. I've worked with HEL's since 1973. I even got to play with ones used in the "Star Wars" projects (ABL). But I never had a chance to do any design of a fiber laser system. Please answer me this. Is the fiber used in the amplifier doped, and if so with what? What are the amplifier's absorption and emission frequencies? The oscillator laser diode operates at what wavelenght? Do you have any energy level diagrams and the timing and energy levels that are involved. Thank you very much for your time and help. Mike J.

Sir, respectfully, I have a technical question. A lot of the lasers light is waisted in an open beam. You can always see the beam, given proper optics. That light is wasted. Unless you focus the beam near infinity, then cram the beam into a fiber wire and take all the normally wasted light to increase the density of the beam. What happens without the seed lasers??? Think of it this way. Your holding a high-powered pointer thur a magnifying glass to its smallest point on to a glass top table. What do you see the laser looks like on the other side of the glass...Super diffused. That doesn't happen in the fiber. No room to diffuse. It harnesses the light that would normally be wasted, and it does that from 16 lasers. Not a capacitor, its a barrel. Could I be right?

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

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

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.

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.

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.
