Compared with mechanical processing, laser processing has the following advantages, such as wide processing objects, small deformation, high precision, energy saving, small pollution, non-contact long-distance processing, automatic processing and other remarkable advantages. Narrow cutting, fine carving, can cut through the blind groove at will; It can be used in ultra thin, fragile, brittle, soft, hard and synthetic materials; Cutting speed is fast; No tool wear; Easy to control and control by computer: easy to work in pipeline. With the development of optical, mechanical and electrical, material, computer and control technology, it has gradually become a new processing technology.
Laser lens has the characteristics of high directivity, coherence and high intensity, so it is easy to obtain high luminous flux density. It focuses the strong beam on the medium, and changes the properties of the material by using the process of interaction between laser and material. This is laser processing. Generally speaking, it is to generate high energy beams through specific media materials, and control the beam. When the beam is emitted to a certain point on the surface of the object - the matter at this point melts or vaporizes rapidly due to high temperature, thus achieving the predetermined material form we need, namely, controlling the energy, speed, direction of the laser The path of walking changes the shape of matter. To meet our needs is laser processing.
As a new type of light source, laser has the characteristics of good directivity, high brightness, good monochromatic and high energy density. Laser based laser industry has developed rapidly in the world. It has been widely used in industrial production, communication, information processing, medical and health, military, cultural education and scientific research. According to statistics, from high-end fiber to common barcode scanners, the market value of laser related products and services is up to trillion dollars a year.
The laser industry has formed a complete and mature industrial chain distribution, and the upstream mainly includes laser materials and supporting components, and the middle reaches mainly includes various lasers and supporting equipment, while the downstream is mainly laser application products, consumer products and instruments. The domestic laser market mainly includes laser processing equipment, optical communication devices and equipment, laser measuring equipment, laser, laser medical equipment, laser component, etc. the application lies in the industrial processing and optical communication market, which accounts for nearly 70% of the market share.
At present, the laser industry in China is mainly used in laser processing, medical treatment and other industries, including 12% of the research and development fields, 32% of the materials processing fields, 12% in the communication field, 14% in the information field, 20% in the medical field, 9% and 1% in measurement and other fields.
