No it isn’t. These are pulse lasers, unlike your co2 which is as a cw (continuous wave). They pump up and then the q breaks down and it dumps what’s in the fibers, this is part of a amplification stage in LASER.
This graphic is from my JPT M7 MOPA manual. Yours is 5nS pulse width (q-pulse), if I recall.
Without physics, they wouldn’t work at all. There’s a lifetime number of them of them out there to learn about. This is a JPT video on how a MOPA works.
As far as it’s uses, there must be somewhere these are used or they wouldn’t build them. I’ve seen similar machines running at around 980nM (shorter wavelength, higher frequency).
Good luck.
