[0002] Laser engraving is one of the most common applications of laser systems. Based on the mechanism of interaction between the laser beam and the material, laser processing can be broadly divided into two categories: laser thermal processing and photochemical reaction processing. Laser thermal processing refers to the process of completing the process by utilizing the thermal effect generated when a laser beam is projected onto the material surface, including laser welding, laser engraving and cutting, surface modification, laser marking, laser drilling, and micromachining. Photochemical reaction processing refers to the process of initiating or controlling a photochemical reaction by using a laser beam to irradiate an object, with the help of high-density laser high-energy photons. This includes photochemical deposition, stereolithography, and laser engraving and etching.
