抽运光模式对DPAL输出特性的影响

Firstly, according to the theory of three-level laser system I've drawn the three-dimensional rate equations, then using Euler's method to solve equations, combined with boundary conditions of the laser system running, the model iterative solver is completed. I simulate the pattern matching factor on the system by changing the laser beam radius. The optimization of the laser output provides a reference. When pattern matching is in the best condition, calculation of the impact on the medium length of the laser output and threshold values is done. In the fixed pump input, we simulate the pump light focused on output changes of different media positions and the laser obtained the optimum focus position. Finally, we calculate the relationship between the laser and the pump light with different coupling reflectivity
