I had a look at that datasheet, it does as low as 10ns on time, but the problem is the rise/fall time of the shutter is nearly 3ms. too slow, because by the time I issue the command to open the shutter, it takes 3ms before it finally opens, my measurement window has passed 5 times before that...

Ya, well at this point I am not sure if I need to exceed the currently recorded CW calculations. But ill keep that in mind. Need to find a suitable transistor.

Thanks. I am aware the PIC/AVR isnt fast enough, thats why I mentioned in my post that i probably could use a one-shot or some other timing method. Anyway... I took a look at that IC, and the max current is only 400ma. If i needed to go to a higher laser diode power, that IC is ruled out...

I am using it for measurement. The numbers I mentioned are power consumption of the CW Diode I currently have. I incorrectly stated output power, Sorry. Not too sure of the output power, but that isnt important at this point, but I would like this adjustable in case I want to try another CW...

Bump. Nobody?

Hey guys, I am new here with a quest of information about building a driver. I have an 808nm diode that has these specifications that I measured while it was in operation with a constant-current driver Diode Voltage Drop: 1.9V Diode Current Consumption: 374mA Calculated Diode output power...
