    Instructions for use:

    1) Directly connect the electricity to the light; be careful not to irradiate the output fiber to the eyes and skin.

    2) Connect the power supply to power on directly, red is connected to the positive pole of the power supply, and black is connected to the negative pole of the power supply; or according to the label on the power cord, 5V is connected to the positive pole and GND is connected to the negative pole.

    3) Please be careful not to bend the output optical fiber; pay attention to keep the output optical fiber head clean. If there is an obvious power drop, please clean the output head with a special tool or replace the optical fiber output head in the case of power failure.

    4) If you need to adjust the laser wavelength, please use a random serial connection line to connect the laser serial port and the computer serial port (RS232); Install the laser temperature control software and run it. The software is written in Labview. You need to Labview the operating engine and Visa operating engine environment. Installing the temperature control software will automatically install the required engine. The temperature dependence of the laser wavelength adjustment is ~ 10pm/°C.

    5) When installing, try to ensure that the laser has good heat dissipation conditions, and the laser can be fixed on a large area of metal liner.
