Guidelines are provided for driving laser diodes, including using special driver circuits to produce either a constant regulated voltage or constant current. Two main types of laser diodes are described: double heterostructure lasers and vertical cavity surface emitting lasers. Laser diodes find wide use in telecommunications as light sources for fiber optic communication, as well as in barcode readers. Many applications utilize the directed energy property of the optical beam produced by laser diodes.
