Precautions for installing and using laser tubes！

1. Please connect the cooling water first when using it. Use the principle of low inlet and high outlet. Adjust the position of the water outlet pipe to ensure that the cooling water fills the cooling pipe and there are no bubbles in the pipe before turning on the power. Requirements: Use soft water (distilled water or purified water) for cooling water, and always pay attention to the water temperature of the cooling water. The water temperature should be controlled in the range of 25℃-30℃, not too high or too low, especially in summer. Once the water temperature is found to be too high, the cooling water should be replaced in time or the machine should be shut down for a period of time: In cold areas, the cooling water should not freeze, especially after the laser is shut down, the cooling water should not be allowed to remain in the laser tube to avoid freezing and bursting.

2. The two supporting points of the laser tube should be at the point of 1/4 of the total length of the laser tube, and the flow rate of the cooling water should be 2L-4L/minute; otherwise, the effect will be poor, it will cause mode jumping, the light spot will change to several points, resulting in a decrease in power; the cooling water return port must be covered with water in the water tank, otherwise the cooling water in the laser tube will not be filled every time the machine is turned off and on.

3. Pay attention to protecting the output window of the laser, avoid the smoke generated during the working process (including the debugging of the optical path) from splashing onto the output window surface, prevent the outer surface of the output window from being contaminated, and the power will decrease. At this time, you can use absorbent cotton or silk cloth dipped in anhydrous alcohol to gently wipe the outer surface of the output window;

4. During the debugging process, adjust the laser support point or rotate the laser position to achieve the output effect, and then fix the laser.

5. Please be sure to pay attention: avoid dust accumulation near the high-voltage electrode, keep it dry, and keep the high-voltage end as far away from the metal as possible to prevent high-voltage ignition and discharge.

6. During the use of the laser, scale should not be formed in the cooling tube to avoid cooling water blockage and poor heat dissipation. Once found, 20% dilute hydrochloric acid can be used to clean the cooling tube to remove scale.

7. The laser is a glass product and is fragile. Avoid local force during installation and use.

8. Rationally apply laser tubes to save laser energy. The working current point of the laser tube is 16 mA.
