Very fast switching (laser control)
Posted: Fri Jul 29, 2022 1:19 pm
Hi guys,
I try to control 2 different lasers at a very fast rate (~1MHz). I need to choose which of the four are on/off for each 1us (laser diodes are capable of toggling at these speeds, that's not a problem). I can control the lasers by just giving a 3.3V-5V signal. Is there a way to do this with Red Pitaya?
I tried some other boards like raspberry pi and arduino but the problem was both their speeds (this shouldn't be a problem for red pitaya) and each transition took different time (going from 01 to 10 takes 1.5us while going from 11 to 00 takes 1.3us).
Thanks!
