10.08.2010 G145PU23W.doc 3 of 3 typical performance curves notes 1. laser beam is harmful especially for your ey es. don't look at the laser beam directly. 2. lifetime of the diode laser variated with the operating temperature inversely. we advise that the tec cooler should be used to keep the temperature suitable. 3. for turning on the diode laser, please increase the current gradually to the specified operating value. for shutting down the diode laser, please decrease the current to zero gradually, and then turn off the power. 4. please wear staticproof bracelet when operating. 5. please connect the pins of the diode laser correctly as the picture showen in the manual. 6. the operating current must less than the rated current. otherelse the diode laser should be damaged. 7. the fiber facet should be keep clean befor the diode laser is operating. 8. please use the constant-current source to avoid the surge. 9. diode laser should be short circuit when stop using. 10. bend diameter of the fiber must be la rger than 4cm temporarily and 8cm permanently.
