cool, thanks for the info, I have a few DPSS that have two TEC's and an analog driver that I think may have analog control or can modded for that, my other green DPSS is a monster class 4 beast (I was hired to realign that thing and ended up just buying it, we found out the hard way that it can't be used on the road, it falls out of optical alignment with vibration , it's happy to just sit on a table and do it's thing) and it has two TEC's as well in a future build I will try that.
I suspected a single TEC would suck just not to this level..
The smaller two TEC lasers are by Crystalaser and I can't find pump diodes for them so over the years I am down to 3 and they are all running at end of life, the pump is at full power for 25mw out, I am told they use an A-mount pump and can't find replacements.
My preference is 532nm green over the 520 green but for one projector I am making I switched to a 520nm after I ran into this characteristic, was hoping it was just the cheapness of the laser.
Thankyou for the info
