| HL6504FM Visible High Power Laser Diode for DVD-RAM ADE-208-825 (Z) 1st Edition Nov. 1999 Description The HL6504FM is a 0.66 m 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 DVD-RAM, and various other types of optical equipment. Hermetic sealing of the small package ( 5.6 mm) assures high reliability.
