SLD323XT

SLD323XT 1W High Power Laser Diode Description The SLD323XT 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 = 1.0W Low operating current: Iop = 1.4A (Po = 1.0W) Flat package with built-in photo diode, 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 = 1.0W, 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 Function TE cooler (negative) Thermistor lead 1 Thermistor lead 2 Laser diode (anode) Laser diode (cathode) Photodiode (cathode) Photodiode (anode) TE cooler (positive) 1.1 2 15 –10 to +30 –40 to +85 W V V °C °C Warranty This warranty period shall be 90 days after receipt of the product or 1,0...
