摘　　要：A high power all-fiber laser is experimentally studied.A monolithic fiber laser system with only one stage of resonator cavity is constructed and 404-W continuous wave（CW） output power is obtained.Its opticalto -optical conversion efficiency is up to 64%.The laser central wavelength is at 1081 nm with the spectral full-width at half-maximum（FWHM） of 2 nm.The laser setup can work with excellent stability;in the long time of high power operation,no thermal distortions or damages are observed.A high power all-fiber laser is experimentally studied.A monolithic fiber laser system with only one stage of resonator cavity is constructed and 404-W continuous wave（CW） output power is obtained.Its opticalto -optical conversion efficiency is up to 64%.The laser central wavelength is at 1081 nm with the spectral full-width at half-maximum（FWHM） of 2 nm.The laser setup can work with excellent stability;in the long time of high power operation,no thermal distortions or damages are observed.
