HL6513FM
Visible High Power Laser Diode for DVD-RAM
ADE-208-1466A (Z)
Rev.1
Jan. 2002
Description
The HL6513FM is a 0.65
µm
band AlGalnP laser diode (LD) with a multi-quantum well (MQW) structure.
Its beam divergence (parallel to the junction) has a small variation to the optical output power. The
characteristic makes it possible to suppress the variation of spot size between higher and lower output
powers. Therefore, it is suitable as a light source for large capacity rewritable optical disc memories, such
as DVD-RAM, and various other types of optical equipment. Hermetic sealing of the small package (φ
5.6mm) assures high reliability.
