1W High Power Laser Diode
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).

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.
