| HL6501MG Visible High Power Laser Diode for DVD-RAM Description The HL6501MG is a 0.65 m 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, such as DVD-RAM, and various other types of optical equipment. Hermetic sealing of the small package (5.6 mm) assures high reliability. Application * Optical disc memories * Optical equipment Features * * * * High output power: 35 mW (CW) Visible light output: p = 658 nm Typ Small package: 5.6 mm Low astigmatism: 6 m Typ (PO = 5 mW) 126 HL6501MG Absolute Maximum Ratings (TC = 25C) Item Optical output power Pulse optical output power Laser diode reverse voltage Symbol PO PO (pulse) VR(LD) Value 35 50 * 2 30 -10 to +60 -40 to +85 Unit mW mW V V C C Photo diode reverse voltage VR(PD) Operating temperature Storage temperature Topr Tstg Note: Pulse condition: Pulse width = 100 ns, duty = 50% Optical and Electrical Characteristics (TC = 25C) Items Optical output power Pulse optical output power Threshold current Operating voltage Slope efficiency Lasing wavelength Beam divergence parallel to the junction Beam divergence parpendicular to the junction Monitor current Asitgmatism Is AS 18 0.05 -- 22 0.3 6 26 1.5 -- deg. mA m PO = 30 mW PO = 30 mW, VR(PD) = 5 V PO = 5 mW, NA = 0.55 Symbols Min PO PO(pulse) Ith VOP s p // 35 50 30 2.1 0.5 645 7 Typ -- -- 45 2.6 0.75 658 8.5 Max -- -- 70 3.0 1.0 665 10.5 Units mW mW mA V Test Conditions Kink free * Kink free * -- PO = 30 mW mW/mA 18(mW)/(I(24mW) - I (6mW)) nm deg.
