Alright thanks a lot. But would a test load still work identically to a laser diode, for testing the current settings??
So, then you could put something like 20 or 30 ohms in series with the actual diode when connecting it to the PS, and as you turn up the voltage from around 4V to 7 to 9V you should see the current increase to the 100mA limit you previously set - and you will be pretty safe this way.
The more complex loads made up of a string of diodes and a resistor are more for testing an actual driver.
