    A bit of googling suggests this is a 5 or 7mW device with a forward current of maybe 50mA tops and forward voltage of 1.9V running in the infrared... but how to verify this without frying it, I dont know...

    Laser Diode experimenters website has a lot of info on laserdiodes and power supplies. It seems the only way to know if you're using the right current is to measure the laser output power against the diode spec... which isn't helpful... but this section of the site explains how to test the laseing action in a controlled manner...
