High Power Density 1W Laser Diode
SLD323V
Description
The SLD323V 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
achieved by QW-SCH structure∗2.

Handling Precautions
Eye protection against laser beams
The optical output of laser diodes ranges from
several mW to 3W. However the optical power
density of the laser beam at the diode chip
reaches 1MW/cm2. Unlike gas lasers, since
laser diode beams are divergent, uncollimated
laser diode beams are fairly safe at a laser
diode. For observing laser beams, ALWAYS use
safety goggles that block infrared rays. Usage of
IR scopes, IR cameras and fluorescent plates is
also recommended for monitoring laser beams
safely.
