A laser diode will always have at least three pins. These three pins are defined as input, output, and case (or ground). Laser diodes (LD) are semiconductor devices that convert electrical energy into high-power optical energy. These devices are currently used in the fields of telecommunications and medicine and in industrial cutting and welding applications. This article discusses the characteristics common to laser. Due to their sensitivity to injected current, laser diodes are typically driven by a stable current source., voltage sources or generic power supplies, are too noisy for most applications and can generate voltage and current fluctuations and transients that may damage the laser. The output power of a diode laser is a function of the operating current. Pout = output power; I = current; th = threshold; T = temperature; j = junction (the place where laser radiation originates in the laser chip); Iop = operating current driving the diode laser. Here is a helpful short video on YouTube explaining constant current and constant voltage sources, and why current sources are preferred for controlling laser diodes. Most of them obtain electrical power from the public grid, but there are also battery-operated devices. Figure 2 shows common power supply and ground configurations where the laser anode is connected directly to the power supply; this is a common configuration for commercially-available laser drivers.
