Operating Notes	● Avoid eye and skin exposure to direct radiation during operation. ● ESD precautions must be taken 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 higher than 6A. Soldering point should be close to the root of the pins. Soldering temperature should be lower than 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℃.
Remark	(1) Data measured under operation output at 4W@25℃. (2) A non-condensing environment is required for operation and storage. (3) Operating temperature defined by the package case. Acceptable operating range is 15℃~35℃, but performance may vary.
