Fiber laser marking machine is a laser that uses rare earth element-doped glass fiber as the gain medium. Fiber laser marking machine has become a hot spot in laser physics research in recent years. It is unanimously considered to be a new generation of products that may completely replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, it is easy to form a high power density in the fiber, causing the laser energy level of the laser working material to "reverse the number of particles". When a positive feedback loop ( Form a resonant cavity) to form a laser oscillation output.
Fiber laser marking machine uses laser beams to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the physical changes of the surface material through the light energy, or to burn part of the material through the light energy, showing the desired etched pattern , text, barcode and other graphics.
Features of fiber laser marking machine:
1. The fiber laser marking machine can process a variety of metal and non-metal materials. It is especially advantageous for marking high hardness, high melting point, and brittle materials.
2. It belongs to non-contact processing, no damage to products, no tool wear, and good marking quality.
3. The laser beam is thin, the consumption of processing materials is small, and the processing heat-affected zone is small.
4. The fiber laser marking machine has high processing efficiency, adopts computer control, and is easy to realize automation.
