Characteristics of fiber laser cutting machine
Fiber laser cutting machine laser has many characteristics: First of all, the laser is monochromatic, or single frequency. There are some lasers that can produce lasers of different frequencies at the same time, but these lasers are isolated from each other and used separately. Secondly, the laser is coherent light. The characteristic of coherent light is that all the light waves are synchronized, and the whole light is only It is like a 'wave train'. Once again, the laser is highly concentrated, which means that it has to travel a long distance before it disperses or converges. The laser (LASER) is a light source invented in the 1960s. .LASER is the acronym for 'stimulated light amplification' in English. There are many types of lasers, ranging in size from a few football fields to small grains or salt grains. Gas micro-optical devices include nitrogen-atmosphere lasers and argon. Lasers: solid-state lasers have ruby u200bu200blasers: semiconductor lasers have laser diodes, such as those in CD players, DVDs and CD-ROMs. Each type of laser has its own unique method of generating laser light. Laser technology laser has good monochromaticity , Strong directionality, high brightness, etc. There are thousands of laser working materials that have been discovered, with wavelengths ranging from soft X-rays to far infrared. The core of laser technology is lasers. There are many types of lasers, which can be based on working materials and excitation methods. , Operation mode, working wavelength and other different methods classification. According to different usage requirements.
The fiber laser cutting machine adopts some special technologies to improve the optical quality and individual technical indicators of the output laser. The more widely used unit technologies include resonant cavity design and mode selection, cheek doubling, tuning, Q switching, Mode locking, stabilization and amplification technology. At the end of the 1960s, laser rangefinders began to be equipped with troops, and multi-line types have been developed and produced. Most of them use yttrium aluminum garnet lasers, with a range accuracy of about 5 meters. Because it can quickly and accurately measure the target distance, it is widely used in reconnaissance measurement and weapon fire control systems. Q laser guidance technology. Laser guided weapons have high precision and simple structure. In order to meet the needs of military applications, the following 5 lasers have been mainly developed Technology: ①Laser ranging technology. It is the first laser technology to be practically applied in the military. It is simple, not susceptible to electromagnetic interference, and occupies an important position in guided weapons. In the early 1970s, the laser cutting navigation air bomb developed by the United States Used on the battlefield in Vietnam. Since the 1980s, the production and equipment of laser-guided missiles and laser-guided artillery shells have also increased day by day. However, laser communication technology. Laser communication has large capacity, good confidentiality, and strong anti-electromagnetic interference capabilities.
