0.5W High Power Laser Diode

Description

The SLD322XT is a high power, gain-guided laser diode produced

diode has a high brightness output with a doubled optical density

Fine adjustment of the oscillation wavelength is possible by controlling

the temperature using the built-in TE cooler (Peltier element).

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

Warranty

This warranty period shall be 90 days after receipt of the product or

1,000 hours operation time whichever is shorter.

Sony Quality Assurance Department shall analyze any product that

fails during said warranty period, and if the analysis results show

that the product failed due to material or manufacturing defects on

the part of Sony, the product shall be replaced free of charge.

Laser diodes naturally have differing lifetimes which follow a Weibull

distribution.

Special warranties are also available.
