A high-power all-fiber laser has been designed with a domestic fiber grating as the resonator cavity, and the highest output power of the laser is 468 W. The relationship between the central wavelength of the fiber grating and the output spectral width of the laser is investigated theoretically and experimentally. The experimental optical-optical efficiency can reach 70%, the central wavelength of the fiber grating tends to be larger when the output power increases. The change of the output power in 180 s is less than 0.04% under the highest output power. Source
