The effect of fiber laser engraving is to reveal the deep material through the evaporation of the material's surface, or to mark traces through the physical change of material's 2D/3D surface caused by laser energy, or to burn out some substances by optical energy, then display all kinds of graphics, such as etched letters, patterns, numbers, characters, signs, barcodes and so on. Fiber laser marking system adopts the most advanced fiber laser and ultra high speed scanning system in the world. Optical fiber laser marking machine has high electro-optical conversion efficiency, air cooling, small overall volume, good output beam quality, high reliability, long service life and no maintenance. It can meet the requirements of higher depth, smoothness and fineness of the marker.
