Hi,
I got a laser diode of 50W, 805-810 nm. I did not try it but I was thinking about a laser head for my cnc machine. It has a short fiber coupler and I hope to get a lens for it. I bought a fluid cooler for computer microprocessor I plan to use it for cooling, and I found out an old computer power supply of 3.3 V that I hope to be able to modify for it. Is here somebody did something similar with a laser diode or do you have any ideas how to build it? The first issue is how to control the current of the power supply in the range of 18-45 A with 5V TTL signal? Also, I must modify the power supply as I think it delivers now only 15A. The second issue is how to focus the laser beam? I mean a mechanical construction for it.
Any ideas?
Thank you.
Zoltan
