Nanosecond solid-state UV lasers have a lifetime of up to 12,000 hours

At present, the laser equipment for marking on the market mainly includes carbon dioxide marking machine, optical fiber marking machine and ultraviolet marking machine. Among them, the optical fiber marking machine has a lifespan of 100,000 hours, and the carbon dioxide laser machine has a long lifespan.

Basically, it takes about two years to return to the factory for maintenance, and the main reason is that the UV crystal needs to be replaced. UV laser at work

Ultraviolet rays will ionize the air, and UV crystals are insulators. After ionization, the crystals are charged and adsorb dust particles in the air.

The surface of the crystal is damaged by ultraviolet irradiation. The ultraviolet itself has a short wavelength and is also very easy to damage the crystal.

Basically, the crystal of the UV laser will be damaged when it works for about 12,000 hours, and it needs to be returned to a class 100 clean room to be replaced by a professional optical engineer. In addition, the life of the laser module will decline sharply when the life of the laser module is about 15,000 hours, because the laser damage cannot be On-site maintenance, so it is very important to use the follow-up service of the UV laser marking machine.
