Basod on experimental study of Nd-doped single-mode fiber lasers, we use the fundamental wode Gan-sian function to approximate signal light field and pumping light field distribution, and to obtain analytical expressions for the threshold power and slopeefficicney. Our calculation results agree well with the experimental ones.
