Hello Folks,
I have a 100mw o-like one here, and it should be used in a RGV projector. so i have to build a analog driver for it. Now i heard and read lots about mode hopping and other crap, even tested it myself with a chinese 5mw one at my practice, which indeed had bad beam form and output instabilities.
So is there a way to get those anywhat stable without buying an professional one?
The genius where i worked for a time recommend me to build a OpAmp based PID-Regulator with a photodiode feedback loop which measures a small splitted out amount of the Laser.
Any comments on this please?
