Fiber laser refers to a laser with a rare earth element-doped glass fiber as the gain medium. This kind of laser can be developed on the basis of a fiber amplifier, using the action of pump light to form a high power density in the fiber, resulting in a "particle number reversal" of the laser energy level of the laser working substance. When a positive feedback loop (forming a resonator) is appropriately added, a laser oscillation output is formed.
The structure of fiber lasers is similar to traditional solid-state lasers and gas lasers, and is mainly composed of three parts: pump source, gain medium and resonant cavity. Depending on the number of output wavelengths, fiber lasers can be divided into single wavelength and multi-wavelength types.
Fiber laser is a high-tech device, which can convert light energy into laser energy, which has the advantages of high efficiency, flexibility and reliability, and is widely used in various fields.
OneCommunication:Used as a signal source in fiber optic communication systems, fiber lasers can achieve efficient and high-capacity communication transmission in long-distance and backbone transmission networks. The signal attenuation of fiber lasers is small and the transmission distance is long, which can meet the needs of big data transmission. In addition, fiber lasers can also be used in optical devices, optical communications, and other fields.
IIIndustrialIn industrial production, fiber lasers can be used for cutting, welding, marking, cleaning and other processing processes. For example, in automobile manufacturing, fiber lasers can be used to weld car bodies, cut frames, etc. In addition, fiber lasers can also be used to manufacture high-precision parts such as integrated circuits and miniature sensors.
IIIMedicine:In the medical field, fiber lasers can be used for various diseases, such as myopia, farsightedness, glaucoma and other ophthalmic diseases, as well as cancer diseases such as cancer. Fiber lasers are able to accurately control the size and duration of the beam, effectively ** disease, and do not cause damage to the surrounding tissues.
FourthScientific research: Used as a research tool in the fields of physics, chemistry, biology, etc.
FiveDefense Military:In the military field, fiber lasers can be used in a variety of applications such as laser**, lidar, laser guidance, etc. For example, fiber lasers can be used to create lidar to detect information such as the location and velocity of enemy targets. In addition, fiber lasers can also be used to create lasers**, which can be used to attack enemy targets and render them incapacitated.
SixMeteorology:It is used for meteorological monitoring and forecasting.
SevenAstronomy:It is used for astronomical research, such as the detection of celestial matter.
EightEnvironmental monitoring: Used for environmental monitoring and pollution control.
NineEnergy:It is used in renewable energy fields such as solar photovoltaic and wind energy.
In short, the application field of fiber laser is very wide, and with the continuous development and progress of science and technology in the future, the performance of fiber laser will continue to improve, and we expect its application to have a broader development prospect.
