Precautions
Quality Assurance
After any processing of the laser chip into TO-Can by the customer, the performance, yield and reliability of the
finished product are dictated by customers own handling, assembly, and testing procedures. The performance
will further be affected by environmental conditions and any physical or chemical stress the chips might be
exposed too. Hence the characteristics and reliability of the finished product cannot be guaranteed, and remains
the sole responsivity of the customer.
Safety
Caution: Laser light emitted from any laser diode may be harmful to the human eye. Avoid looking directly
into the laser diode’s aperture when the diode is in operation.
Note: The use of optical lenses with this laser diode will increase eye hazard
ESD caution
Always do handle laser diodes with extreme care to prevent electrostatic discharge, the primary cause of
unexpected diode failure. To prevent ESD related failures, it is strongly advised to always wearing wrist straps,
and grounding all applicable work surfaces, when handling laser diodes
Operating Considerations
We strongly advised to only operate this laser diode with a current source. The current of a laser diode is an
exponential function of the voltage across it. Usage of current regulated drive circuits is mandatory.
Laser diodes may be damaged by excessive drive currents or switching transients
It is advised, to operate the laser diode at the lowest temperature possible, and to never exceed maximum
specifications as outlined in the datasheet. Device degradation will accelerate with increased temperature.
Proper heat sinking will greatly enhance stability and lifetime of the laser diode
