The term laser is an acronym that stands for "Light Amplification by Stimulated Emission of Radiation". SANYO laser diode structure and basic element structure are listed below.

SANYO Laser Diodes Support Advanced Inforamtion Society
SANYO currently markets AlGaAs infrared laser diodes in the 780 - 830 nm wavelength, as well as AlGaInP based red laser diodes in the 635 - 675 nm wavelength. SANYO realized 635 nm AlGaInP laser diode for the first time in the world. The low operating current and high operating temperature are realized by using misoriented substrate and MQW (Strain compensated) active layer. With unique structures developed by SANYO, providing the following features, these laser diodes are highly rated in a broad range of applications including compact discs, CD-R/RW, DVD systems, bar code scanners, laser pointers and printers. SANYO laser diodes are also compatible with multimedia and other new optical equipment on which advanced information societies in future depend.
