Fiber laser marking machine

Fiber laser refers to the use of rare earth element glass fiber as a gain medium of the laser, fiber laser can be developed on the basis of fiber amplifier: under the action of pump light, the fiber is easy to form a high power density, resulting in the laser energy level of the laser working substance "particle number reversal", when appropriately added to the positive feedback loop (constituting a resonant cavity) can form a laser oscillation output.

Fiber lasers are the mainstream technology route of lasers at present, accounting for nearly 50% of the global laser scale. With good beam quality, high efficiency, good heat dissipation characteristics, compact structure and other characteristics, it is widely used in engraving, marking, cutting, drilling, cladding, welding, surface treatment, rapid forming and other material processing fields, known as the "third generation of lasers", with broad application prospects.
Fiber laser applications vary with different output power. According to the different output power of the laser, the fiber laser can be divided into: 1) low-power fiber laser: output power < 100W, mainly used in laser marking, drilling, precision processing and metal engraving, etc.; 2) medium power fiber laser: output power ≤ 1.5kW, mainly used in welding and cutting of metal materials, metal surface refurbishment treatment; 3) high-power fiber laser: output power > 1.5kW, mainly used for cutting of thick metal plates, three-dimensional processing of special plates, etc.
