The laser diode pinout is the guide for us to how to connect the diodes. It may be different according to the laser diode module number. You can see it the following
1.5 Amp Laser Driver, TEC Controller, Mount ( ALL-IN-ONE )
Laser Diode Controller with TEC for Butterfly LD 14 pin SF8XXX-ZIF14
Laser Pointer Audio Modulator - Wiring and Mounting a 650nm Laser Diode
Laser Diode Housing from Hardware Store Parts
Sony 50mW+ 405nm Blue-violet Laser Diode with Photo Diode (TO18 5.6mm) SLD3232VF - OdicForce
I got this diode out of a dvd rom and I would want to know to what type of laser diode this is, and whats the pinout. Thanks for all helpful answers:) :
