Foreign fiber lasers include: IPG, SPI, coherent, etc. Domestic ones include: Raycus Laser, Tianyuan Laser, Han's Laser, etc.;
According to the working medium, lasers can be divided into four categories: gas lasers, solid lasers, semiconductor lasers and dye lasers. Among them, semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working substances. Semiconductor lasers are widely used in laser communications, optical storage, optical gyroscopes, laser printing, ranging, and radar.
Fiber Laser (Fiber Laser) refers to a laser that uses rare earth element-doped glass fiber as the gain medium. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, the fiber is easily The formation of high power density causes the "particle number inversion" of the laser energy level of the laser working material. When a positive feedback loop is appropriately added (to form a resonant cavity), a laser oscillation output can be formed.
The application range of fiber lasers is very wide, including laser fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing rollers, metal and non-metal drilling/cutting /Welding (brazing, quenching, cladding and deep welding), military defense and security, medical equipment and equipment, large-scale infrastructure, as a pump source for other lasers, etc.
