I setup the laser with scanners and a FB3 board and the laser was able to display any pattern without any blanking problems, the laser was actually better at modulation then my dual maXYZ!
Sorry to here it died., However I have a question for you.
How did you test the modulation speed?
Also, Looking at what you spec'd for modulation characteristics I find it hard to believe it performed better, seeing that its all over the place instead of linear.
To do a proper speed test requires disassembly and tested with a scope at the diode.
or, at least with a photodetector to a scope.
Also that being a DPSS laser it has to show lag.
Altho that laser may do over 30khz ,,will it do 100khz? linearly.
If it did perform better than what I made than there is something wrong with the laser I provided you.
Just an observation
