Since laser diodes are made of semiconductor materials, they do not require the fragile glass enclosures or mirror alignment typical of gas lasers. The resulting ruggedness and small size allow laser diodes to be used in environments and spaces in which other types of lasers cannot. 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 junction is known as a p-n junction. Because they are exceptionally sensitive to even momentary electrical spikes and reverse voltage, a standard power supply is inadequate and will likely.
