摘要：
An analytical model for dual-end-pumped Nd3+-doped gain-guided and index-antiguided (GG-IAG) fiber laser is established. The corresponding analytical expression of the threshold pump power is obtained by solving the improved rate equations. Pump light propagation and threshold characteristics are both researched. Simulation results show that there are optimum values of N, a and L for the lowest Pth. When a=501 mu m, L=9cm, N=1.8*10(20)cm(-3), R-1s=1, R-2s 0.75, the lowest threshold pump power P th of the GG-IAG fiber laser is about 11.95W, the results of the work may be helpful for the later experiments.
