ESD Caution
Always do handle laser diodes with extreme caution to prevent electrostatic discharge, the
primary cause of unexpected diode failure. ESD failures can be prevented by always wearing
wrist straps, only using a grounding workplace, and following strict anti-static guidelines when
handling the laser diode
Safety Advice
This laser diode emits highly concentrated red light which can be hazardous to the human eye
and skin. This diode is classified as CLASS 3 laser product according to IEC 60825-1 and 21
CFR Part 1040.10 Safety Standards.
Operating Considerations
Operating the laser diode outside of its maximum ratings may cause failure or a safety hazard.
The diode may be damaged by excessive drive currents or switching transients. If the diode is
operated using a power supply, it is strongly recommended to connect the diode with the output
voltage set to zero. The voltage should then be increased slowly and with great caution, while at
the same time carefully monitoring the laser diodes output power and drive current. The laser
diode will show accelerated degradation with increased temperature, and it is advised to keep the
case temperature low therefor, by means of heat sinking the device.
