| Abstract: | By approaching of the Gaussian function, the intensity distribution of multi-pumped light with different pumping parameters such as pumping structure, pumping beam waist, gain medium radius and absorption coefficient has been simulated, and the impact of the different pumping parameters on the pumping homogeneity has also been discussed. The conclusion is that the pumping intensity distribution can be strengthened by increasing pumping direction and pumping beam waist, and it can also be strengthened by decreasing the gain medium radius. It also indicates that the absorption coefficient should be moderate. |
