Handling Precautions
Eye protection against laser beams
The optical output of laser diodes ranges from
several mW to 10W. However the optical power
density of the laser beam at the diode chip
reaches 1.5MW/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.
