Fiber laser marking machine can also be called metal laser marking machine. Because it uses a fiber laser, it is a laser that uses a rare earth-doped glass fiber as the gain medium. Under the action of the pump light, it is easy to form a high power density in the fiber, which causes the laser energy level of the laser working material "particle number inversion" "When the positive feedback loop (to form a resonant cavity) is properly added, the laser oscillation output can be formed. The laser wavelength is 1064nm, which belongs to infrared invisible light, and the absorption rate of metal materials for this wavelength is relatively high, so the fiber laser marking machine is mainly used for metal marking.

Many people will have a question: "Can all metals be marked with a fiber laser marking machine?"-Yes, a fiber laser marking machine can mark any metal material, but it is not something The material can be played clearly, in other words: not all metal materials can achieve the desired effect.
