I'm devastated!
Loosing a laser is like loosing a child. It feels like I lost my entire family is a plane crash this weekend...
I now know what caused it...but I still don't know why
The short verison:
Saturday I embedded my 2-3 watt(PBS) home-built lab build laser into my laser system. Spend hours aligning the dichroic mirrors. Hooked up the Flexmod modulation to my Medialas Mamba Black laser hardware/software. 0v = 0.01A 5v=1.2A (well within spec.)
Both lasers died after about 10 seconds of modulation. !!!
Ok, So I thought it must the power supply. So I installed a new commercial regulated PSU. Installed my 1 Watt TEC lab style. Spend Sunday with alignment. (Laser was running for hours during this process @ 1.5A).
Hooked it up to my German hardware/software as stated above.
Less than 20 seconds laser dead!!!!!!
The modulation is killing them and I don't know why. The Flexmod? Can these 445 be modulated?
UPDATE: 20 FEB 2011
My two new Flexmod P3 have arrived and sitting in customs. Should have it before the weekend.
Going to try modulate another 445nm and hopefully it doesn't kill it. Will post results....
