ESD Cautions
The primary cause of diode failure is unexpected electrostatic discharge. To help prevent device failures, be sure to handle devices with extreme care. Users should always wear an ESD wrist strap, ground all applicable work surfaces and follow anti-static techniques when handling diode lasers.
Operating Considerations
Operating the diode laser outside of its maximum ratings may present a safety hazard or cause a device failure. Additionally, excessive drive current or switching transients can damage CW diode lasers. DO NOT exceed the maximum peak optical power. Before turning the power supply on, connect the component to the power supply and ensure the output voltage value is zero. After the component has been successfully connected, increase the current slowly and monitor both the output power and drive current. Device degradation accelerates with increased temperature; therefore, careful attention to minimizing the case temperature is advised. A proper heat-sink for the diode laser on a thermal radiator will greatly enhance laser life.
