Laser diode driver?
I would like to use this circuit (please see photo) for driver a laser diode to engraving wood
-Item Name:ML101U29-25 (Mitsubishi)
Power output: CW 300mW
Pulse Power: 400mW
Working Current: <340mA
I know about this formula I = V/R But in this circuit I am not sure for calculate current .So please could you help me to know how many (mil.amp) I must setting for 9 volts power with maximum output 300mW (with safe laser diode ).
-Or you show me other best circuit
Many thank you.
