Typical Performance Curves
Notes
1. Laser beam is harmful especially for your eyes. Don't look at the laser beam directly. 2. Lifetime of the diode laser varied 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 static proof bracelet when operating. 5. Please connect the pins of the diode laser correctly as the picture shown in the manual. 6. The operating current must less than the rated current. Otherwise the diode laser should be damaged. 7. The fiber facet should be keep clean before 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 larger than 4cm temporarily and 8cm permanently.

Laser safety operating instructions
Laser usage requirements in environment
A ultra-clean environment should be provided for operating the LD. The operating temperature should be controlled at –10 °C … 45 °C.
Laser safety warning signs should be posted in the working place.
The requirements on the power supply driving the LD
Constant-current should be available for power supply. The power supply should have the ability to avoid current or voltage surge at any condition (during start-up, intermittence or open circuit). The surge would result in insta.
