Back Half and Lens Options

AL:Aluminum CU:Solid Copper Back Half CUHL:Solid Copper Half Legth CUDS:Solid Copper With Driver Shelf

NL: No Lens 2EG: Two Element Glass Lens 3EG:Three Element Glass Lens G2: G-2 Glass Lens

All copper back half options make direct thermal contact with the base of 9mm diodes or the base of the copper diode mount on modules for 3.8mm/5.6mm diodes

Aluminum back halfs have for a free floating compact driver to be installed by connected directly to the pins where no additional driver heasinking is required

The 20mm and 25mm Copper with Driver Shelf options have a pocked machined to thermally bond a compact driver in the back of the module for higher current builds

All the drivers I carry except the Blackbuck 8M will work as a compact driver for the above configurations

Here is the Pinout for the diode

Here is a macro shot of the diode decanned. If you see the fifth wire from the right is the ESD protection. The 9mm also sports a much more massive frame than similar 5.6mm diodes for much better thermal efficiency, output stability and life expectancy.

Here is a close up on it.

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

The, "I want to build a laser", Thread

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 2.4A or you diode will suffer thermal runaway and die. For more info on the reason for a constant current driver see this thread.

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.;)
