The Application Of Laser In Life
Was born in 1960, the world’s first laser in 1961 developed the first laser in our country, more than 40 years, fast development of laser technology and application, has combined with multiple disciplines to form multiple application technical field, such as photoelectric technology, laser medical treatment and photonic biology, laser processing technology, laser detecting and measuring technology, laser holographic technology,Laser spectral analysis technology, nonlinear optics, ultrafast laser science, laser chemistry, quantum optics, lidar, laser guidance, laser isotope separation, laser controlled nuclear fusion, laser weapons and so on.The emergence of these intersecting technologies and new disciplines has greatly promoted the development of traditional and emerging industries.
Introduction to Laser Technology Application
Laser processing technology is the use of laser beam and material interaction characteristics of the material (including metal and non-metal) for cutting, welding, surface treatment, drilling, micro-processing and as a light source, identification of objects, such as a technology, the traditional application of the largest field for laser processing technology.Laser technology is a comprehensive technology involving multiple disciplines such as light, machine, electricity, materials and detection. Traditionally, its research scope can be generally divided into:
1. Laser processing system.Including laser, light guide system, processing machine tools, control system and detection system.
2. Laser processing technology.Including cutting, welding, surface treatment, drilling, marking, marking, fine tuning and other processing technology.
Laser welding: automotive body thick and thin plates, automotive parts, lithium batteries, cardiac pacemakers, sealing relays and other sealing devices and a variety of devices that do not allow welding pollution and deformation.The lasers in use at present are YAG lasers, CO2 lasers and semiconductor pumped lasers.
Laser cutting:Automotive industry, computer, electrical cabinet, wood cutting die industry, cutting various metal parts, and special materials, circular saw blades, the force that press a gram, spring washers, electronic parts under 2 mm with some metal plates, steel pipes, tin-coated copper plate, plate, lead plate, phosphor bronze plating, electricity boards, thin aluminium alloy, quartz glass, silicon rubber, below 1 mm alumina ceramic pieces, aerospace industryTitanium alloys used in the industry and so on.The lasers used are YAG laser and CO2 laser.
Laser marking: in a variety of materials and almost all industries are widely used, the current use of lasers are YAG laser, CO2 laser and semiconductor pumped laser.
Laser drilling: laser drilling is mainly used in aerospace, automotive manufacturing, electronic instrumentation, chemical industry and other industries.The rapid development of laser drilling is mainly reflected in the average output power of YAG laser for drilling has been increased from 400W five years ago to 800W to 1000W.At present, the more mature application of laser drilling in China is in the production of artificial diamond and natural diamond wiredrawing die and the production of watches and instruments gem bearings, aircraft blades, multilayer printed circuit boards and other industries.At present, YAG laser and CO2 laser are mainly used, and some excimer laser, isotope laser and semiconductor pump laser are also used.
