HL6545MG
Visible High Power Laser Diode for Recordable-DVD
Description
The HL6545MG is a 0.65
μm
band AlGalnP laser diode (LD) with a multi-quantum well (MQW) structure. It is
suitable as a light source for large capacity optical disc memories, such as H/H type Recordable-DVD, and various
other types of optical equipment.
