Wiring the three pins of the laser diode
It has three pins; two for connecting 5V and GND, and one for turning the laser on and off. Other modules include only two pins: VCC (power supply) and GND. Googling "common pin" indicates it has some relation to ground, but I didn't find a definitive answer. I suspect that the "2" pin on the laser diode is meant to go to ground, since pin 1 is for the photo-diode and pin 3 is for the cathode, but the datasheet doesn't explicitly mention this. Much of the specifics are left to the user as any system can. Some of the 2 pin diodes are made by 3 pin diodes, just cut off 1 pin.

Laser Diode Connection Methods
A laser diode is electrically a. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple PāN diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximiz.

A laser diode is a laser device
A laser diode is a small semiconductor device that emits powerful and precise light using a process known as stimulated emission. These devices are capable of producing an intense laser ray with uniformly sized light waves. This characteristic makes laser beams extremely bright and. A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
