Main factors and Countermeasures of laser power reduction

   For a long time, laser aging and power attenuation will occur. In order to ensure the normal application of laser, we need to understand the main factors and Treatment Countermeasures of laser power reduction.
   1. Check whether the power supply is stable and whether the current reaches the rated t as the current.
   2, check whether the mirror output of fiber laser collimating output mirror is polluted. If there is pollution, you can use a cotton swab to smear with absolute alcohol and gently wipe it. You can not scrape the mirror mask layer.
   3. Check whether other optical lenses are polluted, such as red light stage beam mirror, galvanometer and field mirror.
   4. Check whether the output light of the laser is blocked (ensure that the output end of the isolator and the galvanometer port are at the same level during installation).
   5. After 20000 hours of laser application, the power has a certain attenuation, which is a normal power loss.
   6. During the marking process, there is wire breakage, which is generally caused by signal interference. The leads of weak current and strong current can not be bound or walked on one side at the same time. The signal wire with shielding function is selected as the signal wire; The second is that the ground of the power supply has no effective contact.
