Precautions:

1. Avoid direct exposure of the laser to the eyes and skin when the laser is working. Even if a very weak laser enters the eyes, it may cause serious damage after the convergence of the eyes.

2. The laser requires a stable driving power supply to avoid surges. The instantaneous reverse current and reverse voltage cannot exceed the limit value, otherwise the components will be damaged.

3. Semiconductor lasers are sensitive to temperature. Working at high temperatures will reduce the conversion efficiency and accelerate the aging of components. They need to be used under sufficient heat dissipation or cooling conditions.

4. The laser should be used at rated current and rated power. Excessive output power will accelerate the aging of components.

5. The laser is an electrostatically sensitive device. Anti-static measures must be taken during transportation, storage and use.

6. The laser should be stored or operated in a dry and ventilated environment to prevent condensation from damaging the laser.

7. The light-emitting surface (cavity surface) is one of the key parts of the laser. Avoid any operation to damage the cavity surface. During the use of the device, ensure that the die is not contaminated and prevent mechanical damage.

8. The optical fiber cannot be bent at a large angle, and the bending diameter must be greater than 300 times the optical fiber diameter.
