Laser etching achieves material removal by focusing a high-energy laser beam to instantly evaporate or melt the material surface.
Laser etching is a processing method that uses high-energy laser to act on the surface of a material, causing chemical or physical changes, in order to achieve material thinning or drilling. In laser etching, the laser beam will generate a very high light energy density through the focusing lens, causing the material surface to instantly evaporate or melt, or even vaporize, forming small holes, depressions, or structures.
Laser etching has advantages such as high precision, high efficiency, and high quality, and can be used to manufacture micro structures and small-sized devices. Compared with traditional mechanical processing methods, laser etching can achieve higher morphology complexity and processing quality, fully meeting the requirements of micrometer level processing.
Laser etching is widely used in the manufacturing of micro devices such as microprocessors, biochips, fiber optic communication devices, solar panels, as well as surface texture processing, anti-counterfeiting processing, mold processing, and other fields.
