Abstract

By means of numerical analysis, the distribution of pump light and the output laser power along the fiber with different fiber length has been researched. The experimental research of Nd3 + -doped polarization-maintaining fiber (PMF) laser is reported, which is pumped by 808 nm semiconductor laser. The influence of different fiber winding radius on output power and polarization characteristic of the laser is studied. Double wavelength peak at 1060 nm and 1092 nm are gained. The maximum output power of the laser is 7.35 W at 1060 nm, the slope efficiency is 58.3％..
