Fiber laser means a laser that uses a rare-earth-doped glass fiber as a gain medium. A fiber laser can be developed on the basis of an optical fiber amplifier: Under the action of pump light, high power density can be easily formed in the fiber, resulting in a laser of the laser working substance. The energy level "particle number reversal" can form a laser oscillation output when a positive feedback loop (constituting a resonant cavity) is appropriately added. Fiber laser marking machines use laser beams to mark permanent surfaces of various substances. The effect of marking is to reveal the deep material through the evaporation of the surface material, or to “burn” the trace by the light energy to cause the chemical physical change of the surface material, or burn off some of the material through the light energy, showing the required etching.
