By working medium, lasers can be divided into gas lasers, solid-state lasers, semiconductor lasers and dye lasers 4 categories. Among them, the semiconductor laser, also known as laser diode, is a semiconductor material as the working material of the laser. Semiconductor lasers have a wide range of applications in laser communication, optical storage, optical gyroscope, laser printing, ranging, and radar.
Fiber laser (Fiber Laser) refers to the use of rare-earth element-doped glass fiber as the gain medium of the laser, fiber laser can be developed on the basis of fiber amplifiers: in the role of the pump light within the fiber is very easy to form a high power density, resulting in the laser energy level of the laser working material, "the number of particles inversion "When a positive feedback loop (constituting a resonant cavity) is properly added, a laser oscillation output can be formed.
Fiber laser has a wide range of applications, including laser fiber communication, laser space telecommunication, industrial shipbuilding, automobile manufacturing, laser engraving laser marking laser cutting, printing roller, metal non-metallic drilling/cutting/welding (brazing, quenching, cladding, and depth welding), military and defense security, medical equipment, instrumentation, large-scale infrastructure, as the pump source of other lasers, and so on. The company's products are available in a wide range of sizes and sizes.
