Sanyo Laser Databook Schematic

What is Laser Diode

The term laser is an acronym that stands for "Light Amplification by Stimulated Emission of
Radiation".

SANYO Laser Diodes Support Advanced Information 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.

• A full line-up includes index guided short-wavelength, low-noise, high output power

• Long life and high reliability

• A stabilized fundamental transverse mode

• 9 mm, 5.6 mm diameter packages and frame type

• Pin connections compatible with various power supply systems
