What are the types of laser heat treatment

Laser engraving is the most common application of laser systems. According to the mechanism of the interaction between the laser beam and the material, laser equipment，laser processing can be roughly divided into two categories: laser thermal processing and photochemical reaction processing.

Laser thermal processing refers to the use of the thermal effect generated by the laser beam projected on the surface of the material to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser laser marking, laser drilling and micromachining;

Photochemical reaction processing refers to a processing process in which a laser beam is irradiated to an object and photochemical reactions are induced or controlled by high-density laser high-energy photons. Including photochemical deposition, stereolithography, laser engraving and etching, etc.
