The main reasons why lasers can be used for material etching processing are as follows:
1. Laser beams have a very high energy density
Due to the interaction between the laser beam and the material surface, the energy density formed can far exceed that of traditional processing methods. High energy laser beams can instantly evaporate, melt, or even vaporize the surface of materials, achieving the purpose of etching.
2. Laser etching has good controllability
Laser etching is a non-contact processing method that can achieve precise control of parameters such as depth, width, and shape of etching by adjusting laser parameters, material properties, lens focal length, and other factors. Therefore, laser etching has become an effective technical means for material etching and processing.
【 Conclusion 】
Laser etching is a common precision machining method that can be used to produce small structures. Laser interacts with the material surface through air and lens, forming a high-energy density light source that evaporates or even vaporizes the material surface to achieve material etching. Laser etching has the advantages of high precision, high efficiency, high quality, and strong controllability, and is widely used in the manufacturing of micro devices, surface texture processing, anti-counterfeiting processing, mold processing, and other fields.
