I have the issue that then I activate "stand-by beam suppression" on a pl 520 it seems to need ~100micro seconds to wake up from idle.
This can be seen on various test-pasterns and graphics. When a white beam goes on from being blanked, the green needs considerable more time to recover than the PL450B and HL63603TG. Making the beam magenta for the first 3 points.
When sbs is disabled everything works as a charm. ( But to achieve some lineairity, I need to add some bias, which in turn adds an annoying beam when it should be off.)
Did anybody find a solution for this? (I'd rather not install a shutter)
Can I remedy this by applying a sub-threshold-bias current ?
Other thing I noticed, lasing threshold is pretty sensitive to temperature.
Funny, because I didn't noticed it before, and I don't recall having read about it here on the forums.
Maybe it's because dpss modulates like a wet towel, all red and blue diodes seem to behave perfectly in comparison.
Since green diodes has the promise of perfect modulation, I may be hyper critical on all modulation characteristics, expecting a ruler-flat response also when I lower the intensity of my projector to 10%.
I guess I have found another good reason to tec my diodes.
