Caution for Using Laser Diodes
(1) A laser beam is harmful to human eyes. Never look at active laser directly or through lens.
(2) Caution must be exercised in preventing electrostatic damage while handling the laser diode. To ensure
human grounding (via 1 MΩ) , use a conductive mat on the floor, conductive sole shoes, conductive containers,
etc. Always ground the tip of solder iron.
(3) Laser diode can be damaged by abnormal pulses from nearby equipment. For example, fluorescent lamps
should never be turned on/off near laser diodes.
(4) Never exceed the absolute maximum rated values. It is especially important not to exceed the absolute
maximum output even momentarily.
(5) Check the transition characteristics of the entire driving circuit including the power supply. Take appropriate
measures to avoid events such as spike current generated when the power switch is turned on/off which may
exceed the laser diode's maximum rating.
(6) The maximum rated values are set for ambient temperature of 25°C. The maximum allowable optical
power output will drop as the temperature rises, resulting in limitation of operating range. Allowance must be
made for this phenomenon.
(7) We recommend keeping the actual design targets below 2/3 the maximum ratings.
(8) Appropriate protective circuitry must be provided in each laser circuit.
(9) Attention must be paid to providing adequate means for heat dissipation.
