Laser engraving principle

😊Is produced by the transition of atoms (molecules or ions) and is caused by spontaneous radiation. Lasers are light, but unlike normal light, lasers are very pure in color because they rely only on spontaneous emission for a very short period of time, and the subsequent process is completely determined by excitation radiation. Yes, there is almost no divergence. , Engraving machine, very high emission intensity. In addition, it is a laser with high coherence, high intensity, and high directivity. After the laser is generated, it passes through a reflecting mirror and is irradiated to the work piece through a focusing mirror, and the work piece (surface) is exposed to strong heat and the temperature rises. It rises sharply. The points melt or evaporate rapidly due to the high temperature, and the processing is performed according to the operating path of the laser head.

The application of laser processing technology in the advertising industry can be divided into two main processing methods, laser cutting and laser engraving, but there are some differences in the operation process for each processing method.
