Diameter of light beam of fiber laser cutting machine after passing through focusing mirror
[1] After passing through the focusing mirror, the light beam is 3 * 10-5m to 5 * 10-5m after passing through the focusing mirror. Note that slit compensation is generally available. As shown in the following figure:
[2] Optical fiber laser cutting machine is a kind of latest technology, which has been applied to various industries, including metal cutting, glass cutting and carving, etc. Laser is a kind of light, which, like the electroluminescence in nature, is generated by the transition of atoms (molecules or ions) and is caused by spontaneous radiation. Although laser is light, it is obviously different from ordinary light in that laser only depends on spontaneous emission in the first very short time, and the subsequent process is completely determined by stimulated emission. Therefore, laser has very pure color, almost no divergent directivity, engraving machine, and extremely high luminous intensity. The laser has high coherence, high intensity and high directivity at the same time. After being generated by the laser, the laser is transmitted by the reflecting mirror and irradiated on the processed articles through the focusing mirror, so that the temperature of the processed articles (surface) is sharply increased due to strong thermal energy, and the point is rapidly melted or vaporized due to high temperature, thus achieving the processing purpose in coordination with the running track of the laser head.
Therefore, the application of fiber laser cutting machine cutting technology in the advertising industry is mainly divided into two working modes: laser cutting and laser engraving.
