Hello everybody!
I recently begun in the green laser world Well I have a lot of red ones. I bought my first one on eBay (not the best place but the cheapest to begin...).
It's a 5mW green laser. As doing some experiments today I decided to measure how much current it used. I hooked up my multimeter and reads 280mA@2.75 volts... That seems to be a lot, so the diode uses 770mW???
Not sure about the calculation but that seems to be a lot. Let's say that the efficiency is 20%, it would say that it outputs 154mW....
In fact it's impossible, I can see the beam in a dark room but not in daylight. Or is it a big big big leak in infrared?
I hope I messed up in my calculation.
Thanks for your advice!
