SLD322XT

SLD322XT 0.5W High Power Laser Diode Description The SLD322XT is a high power, gain-guided laser diode produced by MOCVD method∗1. Compared to the SLD300 Series, this laser diode has a high brightness output with a doubled optical density which can be achived by QW-SCH structure∗2. Fine adjustment of the oscillation wavelength is possible by controlling the temperature using the built-in TE cooler (Peltier element). ∗1 MOCVD: Metal Organic Chemical Vapor Deposition ∗2 QW-SCH: Quantum Well Separate Confinement Heterostructure Features High power Recommended optical power output: Po = 0.5W Low operating current: Iop = 0.75A (Po = 0.5W) Flat package with built-in photodiode, TE cooler, and thermistor Applications Solid state laser excitation Medical use Material processes Measurement Structure AlGaAs quantum well structure laser diode Operating Lifetime MTTF 10,000H (effective value) at Po = 0.5W, Tth = 25°C Absolute Maximum Ratings (Tth = 25°C) Optical power output Po Reverse voltage VR LD PD Operating temperature (Tth) Topr Storage temperature Tstg Equivalent Circuit TE Cooler N P TH LD PD 1 2 3 4 5 6 7 8 Pin Configuration (Top View) No. 1 2 3 4 5 6 7 8 W V V °C °C Function TE cooler (negative) Thermistor lead 1 Thermistor lead 2 Laser diode (anode) Laser diode (cathode) Photodiode (cathode) Photodiode (anode) TE cooler (positive) 0.55 2 15 –10 to +30 –40 to +85 Warranty This warranty period shall be 90 days after receipt of the product or 1...
