Principle of Optical Fiber Laser Marking System
Fiber laser has become a hot topic in laser physics research in recent years. It is generally considered to be a new generation of products that may replace solid-state lasers in an all-round way. Fiber laser is a kind of laser using rare earth doped glass fiber as gain medium. Fiber laser can be developed on the basis of fiber amplifier. It is easy to form high power density in the fiber under the action of pumping light, resulting in "particle number inversion" of laser energy level of laser working substance, when positive feedback is properly added. The output of laser oscillation can be formed by the loop (which constitutes a resonant cavity). Optical fiber laser marking machine is a kind of permanent marking machine, which uses laser beam to mark various material surfaces. The effect of marking is to expose deep substances through evaporation of surface substances, or to "engrave" traces by physical changes of surface substances caused by light energy, or to burn off some substances by light energy, showing the patterns, words, barcodes and other graphics that need to be etched.

Characteristics of Fiber Laser Marking machine
1. It can process many kinds of metal and non-metal materials. Especially for high hardness, high melting point and brittle materials, marking is more advantageous.
2. It belongs to non-contact processing, no damage to products, no tool wear and good marking quality.
3. The laser beam is fine, the material consumption is small and the heat-affected zone is small.
4. High processing efficiency, computer control and easy automation.
