Handling Precautions
(1) Eye protection against laser beams
The optical output of laser diodes ranges from
several mW to 4W. 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.

(2) Prevention of surge current and electrostatic discharge
Laser diode is most sensitive to electrostatic discharge among semiconductors. When a large current is
passed through the laser diode even for an extremely short time (in the order of nanosecond), the strong light
emitted from the laser diode promotes deterioration and then laser diodes are destroyed. Therefore, note that
the surge current should not flow the laser diode driving circuit from switches and others. Also, if the laser
diode is handled carelessly, it may be destructed instantly because electrostatic discharge is easily applied by
a human body. Be great careful about excess current and electrostatic discharge.
