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.
