Instructions for use
Avoid eye and skin exposure to direct radiation during operation.
ESD precautions must betaken during storage, transportation and operation.
Short-circuit is required between pins during storage and transportation.
Please connect pins to wires by solder instead of using socket when operation current is higherthan 6A. Soldering point should be
close to the middle of the pins. Soldering temperature should be lowerthan 260℃ and time shorter than 10 second.
Make sure the fiber output end is properly cleaned before operation of laser. Follow safety protocols to avoid injury when
handling and cutting the fiber.
Use constant current power supply to avoid surge current during operation.
Laser diode must be used according to the specifications.
Laser diode must work with good cooling.
Operation temperature ranges from 15℃ to 35℃ .
Storage temperature ranges from -20℃ to +70℃.
