Do laser diodes have a maximum voltage, or is it all about the current?
I was looking at some datasheets and some don't have a max voltage, but some have one ~0.3V above the typical voltage.
For example I'm currently testing a red laser diode with my new current regulator at 40mA and pretty much bang on 2.7V.
If I changed this to 40mA at 5V is this going to fry the diode, or does it just use what it needs?
Thanks
