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 anti-

static.

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.
