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 is a growing demand for high power, high efficiency, high beam quality and compact lasers in various fields. Compared with traditional gas and solid state lasers, fiber laser has been developed rapidly because of its high efficiency, miniaturization, excellent beam quality and good heat dissipation performance. Laser pumping is a technology to obtain energy from external energy sources. In order for the fiber laser to output laser, the pump power that provides energy must be higher than the laser threshold of the laser. In order to obtain higher laser power, it is necessary to continuously increase the laser pump power. However, due to the structural characteristics of the optical fiber, the diameter of the optical fiber is usually very small. When the external pump power is relatively large, the optical fiber will generate higher temperature after absorbing energy, which will lead to the damage of the optical fiber. In order to improve the laser output power of the fiber without damaging the fiber material, various laser pumping methods have been developed. The appearance of double clad fiber is undoubtedly a breakthrough in the field of laser pumping, which makes the production of high power fiber lasers and high power optical amplifiers come true. The structure of optical fiber is analyzed, and various laser pumping modes are discussed. The simulation of laser pumping is carried out. The results show that the dual symmetric simultaneous pumping mode is a superior method.
