Listing is for a three 1.5W-2W 445nm blue laser diodes mounted in a 12mm x 30mm copper modules with leads and a high output 405-G-2 lenses. The copper module upgrade provides a huge  improvement  in thermal conductivity over the standard brass module for moving the heat away from the diode to your heatsink which gives a much more stable output from the diode.

Save yourself the headache of pressing and soldering. Just add host, heatsink and driver.


Wire assignment is:

Red +

Black -

White Case





If this is your first laser build here is a great place to start.


 

Diodes are current hungry and as they heat up their internal resistance is lowered causing them to want to draw more current. Don't attempt to connect the diode directly to a fixed voltage source like a battery. You must use a "constant current" power source like a current limiting driver or variable current power supply with the current limited to no more than 1.8A or you diode will suffer thermal runaway and die. For more info on the reason for a constant current driver see this thread.

Here is the Pinout for the diode


If you are looking for a host here are some of the more popular host/heatsink kits that will work with these diodes and if you want something that is not listed in those links that I show in my tutorials below shoot me a message and I can point you in the right direction for them.;)
