Hey all,
I was wondering if I use the information provided in the datasheet below for a 250mW laser diode, if I could just create a simple circuit insuring that the voltage and current was appropriate, just to test it out...
(Simple circuit includes 4x AA batteries in series with - + leads, 2x 51ohm resistors in parallel to = 25.5ohms total resistance, 1x 250mW diode)
This configuration should give the laser diode an estimated 2.685V, 130mA. What I don't understand though is that 2.685V x 0.130A = 0.349W
Can someone chime in and make corrections where needed?
Also can someone explain what threshold current is, and all those other little symbols and stuff?
