Handling Precautions
Eye protection against laser beams
The optical output of laser diodes ranges from
several mW to 1W. 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, uncollinated
laser diode beams are fairly safe at a laser
diode. Generally speaking, however, it is best
NOT to LOCK into laser beams, under any
circumstances. 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.
