So I'm building a simple POV laser projector with a spinning array of mirrors similar to this:
I purchased this laser from Aixiz: 532nm 15mw TTL power adj. laser with DC power supply, AixiZ
The video review on youtube stated that the TTL interface can do between 5-10KHz. Ideally I'd like to modulate it as fast as possible. My question is: what sets the maximum modulation frequency? Is it a property of the diode itself or the TTL? Can I pulse it faster (the arduino can accurately send pulses up to around 200KHz) by bypassing the TTL or is this too complicated and/or not worth it? Also, what will happen if it is pulsed too fast (i.e. no light or kill the diode)?
Sorry for the barrage of questions. Wasn't sure whether to post this in experiments, but figured since it deals with modulation y'all might know better. Thanks for the help.
p.s. last time I was on here was like 3-4 years ago. glad to see this forum is still kickin'
