All-fiber Laser with Narrow Linewidth at 1064nm
By the derivation of the rate equation and power propagation equations,we can obtain the relationship between the output power and the resonator factors of fiber laser based on Fabry-Perot cavity. And it is analyzed by mathematical software,the results conduct the design of this experiment. In this work,resonant cavity consists of Yb-doped double-clad fiber and two fiber Bragg gratings with different reflectivity,which achieves all-fiber laser cavity. In addition,FBG is not only used to select frequency,but also to output narrow linewidth laser. Laser device delivers 10.4W peak output power at 1064.6nm with the narrow linewidth of 0.1 nm,the slope efficiency is 67.8％,and the beam quality factor M2 is measured to be 1.06.
