Laser diode lasers can cause damage to human eyes. When the diode is working, it is strictly forbidden to look directly at the end surface of the diode, not to look directly at the laser through the lens, or to observe the laser through the mirror.
2. The device needs a suitable driving power, the instantaneous reverse current cannot exceed 2uA, and the reverse voltage must not exceed 3V, otherwise it will damage the device. To prevent the surge current when the power supply is cut off. When using an oscilloscope to test the drive circuit, disconnect the power and connect the oscilloscope probe first. If the probe is tested in the case of power, the device may be referenced by the surge current.
3. Devices should be stored or worked in a clean environment.
4. Working at a higher temperature will increase the threshold current, lower the conversion frequency and accelerate the aging of the device. When adjusting the amount of light input, the power meter should be used to detect and prevent more than the rated output.
5. The output power is higher than the specified parameter, which will accelerate the aging of the components.
6. The machine needs to be fully cooled or used in refrigeration conditions. The temperature of the laser diode is strictly controlled below 20 degrees, guaranteeing the life span.
7. Diodes are electrostatic sensitive devices, which can be taken when the human body is in good condition. Anti-static bracelets can be used to prevent static electricity.
8. The output wavelength of the laser is affected by the working current and heat dissipation, so as to maintain good heat dissipation conditions and reduce the temperature of the core at work. The heat sink prevents the laser diode from rising too high in the work.
