Hi,
Thanks to the very patient and informative VDX/Viktor I got started in high power IR!
I managed to snag a very cheap Rofin 976nm 300W CW module off eBay and bought a Meanwell driver for it (50Amps).
Then I removed the fibre coupler and the associalted optics and hooked it up to the driver and a 30V, 13A power supply I had laying around.
It actually lased on the first try but I only got two lines so I might have a couple of broken diodes or they were still below lasing treshold.
My power supply did not take this beating very well and died on me so I will upgrade and try to make som more tests. I also have 1064nm focus optics in the mail but it might take a while due to the virus.
