Infrared laser diode, 1000mW = 1 Watt, there are some cautions in order: This MUST be used with a heat sink at all times!

This is VERY static sensitive and you must use a strap whenever you handle this! The packaging is such that the diode is

isolated from the case. This emits enough power to BURN things and to HARM YOUR EYES. You can't see infrared!

Be careful! Price is for a single diode, of course I combine shipping for purchases of more than one.
