Hi guys,
the time has now come - after more than 2 months on business travelling I'm back at home and finished the driver module for the green laser module from heruurscience - it's a temperature controlled laser!!!
With a simple 2 step current control for the Peltier you can easily adjust any operating temperature for the diode and crystal package - higher beam quality or just more power
During the first tests I was able to get about 180mW of lovely green photons out of this hell machine (1500mA diode current and 24°C/75°F). And at 2300mA - some sweat was dripping - even 220mW for a very short time is no problem.
But with the coated output lenses from "o-like" I was able to achieve even higher levels. Up to 25% increase in power - for just a few cents - believe or not - increadible 260mW of green.
But it there's also an amount of invisible IR, especially quite good focused 1064nm - Among the blind the one-eyed is king :-( But the "o-like" lenses are very good and send back a huge amount of this dangerous shit into the crystal and *tata* comes back as green...
One final part is still missing - I'm looking for a suitable collimator lens. I tested a small one from a blue-ray sleed with acceptable results but this is not the perfect solution. Does anyone of you know where to get spare collimator lenses for green laser (pointers)? May be "heruursciences" has the right one.

p.s. If someone is interested in the details of the driver board just contact me.
