Safety
Caution: Laser light emitted from any diode laser is invisible and may be harmful to
human eye. Avoid looking directly into the diode laser aperature when the device is in
operation.
Note: The use of optical instruments with this product will increase eye hazard.
ESD Caution
Always handle diode lasers with extreme care to prevent electrostatic discharge, the
primary cause of unexpected diode failure. You can prevent ESD by always wearing wrist
straps, grounding all applicable work surfaces, and following extremely rigorous antistatic.
Operating Considerations
Operating the diode laser outside of its maximum ratings my 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 diode lasers may be damaged by
excessive drive current or switching transients. When using power supplies, the diode
laser should be connected with the main power on and the output voltage at zero. The
current shuould be increased slowly while monitoring the diode laser output power and
the driver current. Device degradation accelerates with increased tempereature, and
therefore careful attention to minimize the case temperature is advised. A proper heat
sink for the diode laser on a thermal radiator will greatly enhance laser life.
