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. 04.08.2010 rlt915_150gs.doc 2 of 2
