    Abstract: The use of high-power lasers in the industry has been rapidly advanced by incorporating flexible-fiber-based beam delivery. In order to deliver high-power laser beam to a distant place, the laser beam must propagate through the atmosphere. When the laser beam propagates through a medium, a fraction of the laser energy is absorbed by the medium. Thi... Show More

    Abstract: When the laser transmits in the fiber, it will produce dispersion, and the dispersion is usually expressed by the time delay difference. The reason for dispersion is that the propagation speed of light with different frequencies in the fiber is different with the increasing transmission distance during the transmission of optical signals in the fib...

    Abstract: Fiber laser has many advantages. First of all, fiber lasers are relatively simple in structure, with fewer components than traditional solid state lasers, smaller volume, and easy to integrate into a small area. In addition, the energy conversion efficiency of fiber lasers is very high. The gain medium is rare earth doped glass, which is rich and c... Show More

    Abstract: Fiber laser is a small volume laser using rare earth doped fiber as laser medium. If the fiber laser can emit laser, it must be provided with a certain amount of energy by the outside world. The technology that provides energy for fiber lasers is laser pumping technology. With the continuous development of laser technology and laser devices, there ... Show More
