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: 721mW
its probably a 750mw, because my supply was at 3.2v instead of 3.7v which is what the driver wants. it was from a green laser, but the pump crystal is missing however I dont need the crystal.
I want to be able to modulate this diode to send on-time pulses as low as 40ns, to maybe as wide as 150ns.
The repetition time will be somewhere around maybe 3 to 6 pulses per second.
is there a schematic out there that could do this? I've stumbled across a couple but they are slow, in khz range.
