Description

technical field [0001] The invention belongs to the field of optical fiber technology and laser technology, and in particular relates to a high-power laser hollow-core optical fiber gas-filled coupling terminal. Background technique [0002] As a new type of special low-loss transmission fiber that has developed rapidly in recent years, hollow-core fiber uses its special microstructure to bind light waves in a micron-scale air core for transmission, with low Rayleigh scattering, low nonlinearity, and low transmission. Therefore, it is widely used in power laser systems as an important light-guiding device. When the hollow core fiber is filled with a specific gas and pumped by an external laser, the special gas can be used as the gain medium of the laser to realize the laser output of a specific wavelength. Compared with solid-doped gain fibers, lasers using special gases as gain media can achieve a wider band and higher output power. In particular, high-power hollow-core f...
