| HL6726MG Visible High Power Laser Diode Description The HL6726MG is a 0.68m 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 (5.6mm) assures high reliability. Application * Optical disc memories Features * * * * High output power: 30mW (CW) Visible light output: P = 675 to 695nm Small packege: 5.6mm dia. Low astigmatism: 5m Typ (P O = 5mW) 161 HL6726MG Absolute Maximum Ratings (TC = 25C) Item Optical output power Pulse optical output power Laser diode reverse voltage Symbol PO PO(pulse) VR(LD) Topr Tstg Value 30 45* 2 30 -10 to +60* -40 to +85 2 1 Unit mW mW V V C C Photo diode reverse voltage VR(PD) Operating Temperature Storage temperature Note: 1.
