A Brief Introduction To Fiber Laser Marking Machine

Fiber laser marking machine is a laser with rare earth element 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 fully replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, high power density is easily formed in the fiber, resulting in the laser energy level of the laser working substance "particle number reversal", when properly added positive feedback loop (forming a resonant cavity) can form a laser oscillation output. Fiber laser marking machine uses laser beams to mark permanent marks on the surface of various substances. The effect of marking is to expose the deep substance through the evaporation of the surface substance, or to engrave traces through the physical changes of the surface substance caused by light energy, or to burn off part of the substance through light energy to show the pattern, text, bar code and other graphics that need to be etched.
