| Semiconductor Laser LNC707PS High Power Output Semiconductor Laser Overview The LNC707PS is a near infrared GaAlAs laser diode which provides continuous oscillation in single mode and is stable at low operating current. LNC707PS uses a small package, and is capable of operating continuously at high temperatures with high output (60 mW). It can be used in a wide range of applications as a light source for optical disk memory and optical information devices. In particular, it can be used in making equipment portable due to its low current operations. o1.0 min. o5.6 +0 -0.025 o4.30.1 o3.550.1 Unit : mm 2 0.40.1 1101 LD 1 Junction plane Reference plane 1.00.1 3 PD 2.30.2 1.27 0.25 Reference slot Kovar glass LD pellet Reference plane o1.2max. 3-o0.45 2 High power output : 60 mW Stable single horizontal mode oscillation Small size package 6.50.5 Low current operations : 70 mA (with 60 mW output) 0.5 max. 1 o2.0 Bottom view Features 1.20.1 3 1: LD Anode 2: Common Case 3: PD Cathode Absolute Maximum Ratings (Ta = 25C) Parameter Radiant power Reverse voltage Power dissipation Operating ambient temperature Storage temperature Laser PIN Symbol PO VR VR (PIN) Pd (PIN) Topr Tstg Ratings 60 2 30 100 -10 to +60 - 40 to +80 Unit mW V V mW C C Electro-Optical Characteristics (Ta = 25C) Parameter Threshold current Operating current Operating voltage Oscillation wavelength Radiation angle Horizontal direction Vertical direction Symbol Ith IOP VOP L //* * IR IP X Y CW Conditions PO = 60mW PO = 60mW PO = 60mW PO = 60mW PO = 60mW PO = 55mW/I(60mW - 5mW) VR (PIN) = 5V PO = 60mW, VR (PIN) = 5V PO = 60mW PO = 50mW min 15 70 778 7 17 0.7 typ 25 100 2.0 784 10 21 0.9 0.2 max 35 130 2.5 790 13 25 1.2 0.1 Unit mA mA V nm deg. deg. mW/mA A mA deg. deg.
