Hi!
I meant how fast it is possible to "blink" with them (modulate the signal... turning them on and off repeatedly).
The reason that I'm asking is that I have had fun building a very lo-fi laser projector with a red laser. I modulate the signal (switching the red laser on and off) up to 1 MHz without problem. Now I thought it would be fun to add a green laser, but I heard they are slow and can't be modulated very fast, so I wondered if anyone knows how fast they could be modulated (approximately... I don't expect an exact figure)

Why would you need that kind of speed in a "lo-fi projector"? Are you talking about raster scanning? To your original question, it depends on the quality of the device, but 10-30kHz is a common rating among manufacturers.
I bought some of those acousto-optic modulators (AOM), so I could technically modulate at Mhz speeds (fast for scanners, slow for basically anything else). For the power it takes and the decrease in output it's probably not worth using for that. It's in a box and probably will end up as a never-used project. :| Oh well.
