Hi! Pls help me understand laser power rating. Im newb at electronics.
If the laser diode is rated for ex. 1.6W does it mean, if Im putting 4V to the laser, I shouldn't be pulling more than 400mA since 4V x .4mA = 1.6W even if my laser diode Current rating is 1.7A?
How about when Using Lm317 as constant current regulator, Should I also control voltage so that it doesnt exceed power rating of diode?
