Safety and Operating Considerations
The laser light emitted from this laser diode is invisible and may be harmful to the human eye. Avoid looking directly into the
laser diode or into the collimated beam along its optical axis when the device is in operation.
CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT WILL INCREASE EYE HAZARD.
Operating the laser diode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with
the component must be employed such that the maximum peak optical power cannot be exceeded. CW laser diodes may be
damaged by excessive drive current or switching transients. When power supplies are used, the laser diode should be connected
with the main power on and the output voltage at zero. The current should be increased slowly while the laser diode output
power and the drive current are monitored.
Device degradation accelerates with increased temperature, and therefore careful attention to minimizing the case temperature
is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50°C rather than 30°C.
A proper heatsink for the laser diode on a thermal radiator will greatly enhance laser life. Firmly mount the laser on a radiator
with a thermal impedance of less than 0.5°C/W for increased reliability.
ESD PROTECTION - Electrostatic discharge is the primary cause of unexpected laser diode failure. Take extreme precaution
to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling laser diodes.
