| HL6734FM Visible High Power Laser Diode Description The HL6734FM is a 0.68 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 and various other types of optical equipment. It does not have a photodiode, and the GND pin is not connected to the LD chip. The outline is the same as MG-type (5.6 mm). Application * Optical disc memories * Optical equipment Features * * * * High output power Visible light output Small package Low astigmatism : 50 mW (CW) : p = 675 to 695 nm : 5.6 mm : 5 m Typ (P O = 5 mW) 171 HL6734FM Absolute Maximum Ratings (TC = 25C) Item Optical output power Pulse optical output power Laser diode reverse voltage Operating temperature Storage temperature Symbol PO PO (pulse) VR(LD) Topr Tstg Value 50 65 * 2 -10 to +70 -40 to +85 Unit mW mW V C C Note: Pulse condition : Pulse width = 100 ns, duty = 50% Optical and Electrical Characteristics (TC = 25C) Item Optical output power Threshold current Operating voltage Slope efficiency Lasing wavelength Beam divergence parallel to the junction Symbol PO Ith VOP s p // Min 50 30 2.1 0.5 675 7 16 -- Typ -- 50 2.6 0.7 685 8.5 19 5 Max -- 70 2.8 0.9 695 11 23 -- Unit mW mA V Test Conditions Kink free -- PO = 50 mW mW/mA 30 (mW) / (I(40 mW) - I (10 mW)) nm deg. deg. m PO = 50 mW PO = 50 mW PO = 50 mW PO = 5 mW, NA = 0.55 Beam divergence parpendicular to the junction Asitgmatism AS 172 |
