Visible High Power Laser Diode
ADE-208-601B (Z)
3rd Edition
May 1998
Description
The HL6738MG is a 0.68 µm band AlGaInP laser diode (LD) with a multi-quantum well (MQW) structure.
It is suitable as a light source for large capacity optical disc memories and various other types of optical
equipment.
Hermetic sealing of the small package (φ 5.6 mm) assures high reliability.
