Precautions:
1. When the laser is working, avoid the laser directly hitting the glasses and skin. Even if a very weak laser enters the eyes, it may cause serious damage through the convergence of the eyes.
2. The laser needs a stable driving power supply to avoid surges, and 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 temperature will reduce the conversion efficiency and accelerate the aging of components. It needs to be used under the condition of sufficient heat dissipation or cooling.
4. The laser should be used under the rated current and rated power. If the output power is too high, the aging of components will be accelerated.
5. The laser is an electrostatic sensitive device, and anti-static measures must be taken during transportation, storage and use.
6. The laser should be stored or worked 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 damage to the cavity surface. During the use of the device, ensure that the die is not polluted and prevent mechanical damage.
8. The optical fiber should not be bent at a large angle, and the bending diameter should be greater than 300 times the diameter of the optical fiber.
