Compared with mechanical processing, laser processing has the following advantages: wide processing objects, small deformation, high precision, energy saving, small pollution, non-contact long-distance processing, automatic processing and other significant advantages. It has narrow cutting seam, fine carving, and can cut blind groove without penetration at will; it is convenient to act on ultra-thin, fragile, brittle, soft and hard materials and synthetic materials; it has fast cutting speed; it has no tool wear; it is easy to CNC and computer control; it is convenient for assembly line operation. With the development of optical, electromechanical, material, computer and control technology, it has gradually become a new processing technology.
Laser lens has the characteristics of high directivity, coherence and intensity, and it is easy to obtain high luminous flux density. It focuses the strong beam on the medium, and uses the process of interaction between laser and matter to change the nature of matter, which is laser processing. Generally speaking, it is excited by a specific medium material to generate a high-energy beam and control the beam. When the beam hits a certain point on the surface of the object - the material at that point melts or vaporizes rapidly due to high temperature, so as to achieve the predetermined material form we need. That is to change the material form by controlling the energy, speed, direction and walking path of the laser to meet our needs The demand is laser processing.
As a new type of light source, laser has the characteristics of good directivity, high brightness, good monochromaticity and high energy density. The laser industry based on laser has developed rapidly in the world, and now it has been widely used in industrial production, communication, information processing, health care, military, cultural education and scientific research. According to statistics, from high-end optical fiber to common barcode scanners, the market value of laser related products and services is up to trillions of dollars each year.
The laser industry has formed a complete and mature industrial chain distribution. The upstream mainly includes laser materials and supporting components, the midstream mainly includes various lasers and supporting equipment, and the downstream mainly includes laser application products, consumer products and instruments. The domestic laser market mainly includes laser processing equipment, optical communication devices and equipment, laser measurement equipment, laser, laser medical equipment, laser components and so on. The application lies in the industrial processing and optical communication market, which occupy nearly 70% of the market share.
At present, China's laser industry is mainly used in laser processing, medical and other industries, including 12% in scientific research and development, 32% in material processing, 12% in communication, 14% in information, 20% in medicine, 9% in measurement and 1% in other fields.
