Fiber lasers have a wide range of applications, including laser fiber optic communications, laser space telecommunica- tions, industrial shipbuilding, automobile manufacturing, laser-engraving laser-marked laser cutting, printing rollers, metal nonmetallic drilling, military defense security, and medical instrumentation equipment. , large-scale infrastructure construction, as a pump source for other lasers, etc. So what are the advantages of fiber lasers , do you know?
First of all, let's take a look at what is a fiber laser
Fiber laser refers to a laser that uses a rare-earth-doped glass fiber as a gain medium. Fiber lasers can be developed based on fiber amplifiers. Under the action of the pump light, the high power density is easily formed in the optical fiber, which causes the laser energy level of the laser working substance to “count the number of inversionsâ€. When a positive feedback loop (constitutes a resonant cavity) is properly added, a laser oscillation output can be formed.
[What are the advantages of fiber lasers]
1. The cost is low and continues to decline The gain medium of the fiber laser is glass fiber, while the manufacturing cost of the glass fiber is very low, and the glass fiber technology is very mature. In addition to the gain medium, the main component of the cost of another fiber laser is its pumping. With the development of optical communication technology and the rapid expansion of market capacity, semiconductor pumping of fiber lasers has shown a decreasing trend. Therefore, low cost is one of the significant advantages of fiber lasers.
Fiber Lasers Advantage 2. Can Have Higher Power One of the main limiting factors of laser power is heat dissipation performance, because fiber lasers use fiber as the gain medium, which makes them have a larger surface area under the same volume, which also makes the optical path. The excellent thermal performance means that it can withstand higher laser power. While other types of lasers are considering increasing the laser power, they also have a hard time solving the heat dissipation problem of the gain medium. This feature is unique to fiber lasers.
3, fiber optic road maintenance-free
The optical path of the fiber laser is mainly composed of glass fiber and other optical fiber components, and the optical fiber and the optical fiber component are connected by optical fiber fusion technology, which makes the optical path of the laser as a whole once completed. In practice, it has been proven that such a structure can work stably for a long time without maintenance, which is excellent compared with the frequent need for maintenance of gas or other solid-state lasers. However, it is not as unrepairable as a semiconductor laser, and its entire optical path maintenance and repair is also operational.
4, superior adaptability to the environment between the optical fiber and fiber optic components is connected by optical fiber fusion technology, so that the entire optical path is completely enclosed in the optical fiber waveguide, which means that it is easy to achieve isolation from the outside world, which allows the laser can be away from the light point, can be Lasers are introduced into previously difficult-to-reach locations where the light spots can be easily moved and changed, and the fibers are very small and flexible, so that output light can pass through narrow gaps or travel long distances along small pipes. At the same time, with the advantages of fiber optics, fiber lasers can perform in any harsh working environment and have a high tolerance to dust, vibration, shock, humidity, and temperature.
Xiao Bian concludes: The above introduced the advantages of fiber lasers and hoped to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
