| Abstract: | Regarding frequency doubling process as an intracavity loss which changes with the transformation of the fundamental photon number,the four-level nonlinear rate equation of passively Q-switched laser is modified,and the four-level nonlinear rate equation of passively Q-switched green laser is summarized.The output characteristics of the LD pumped Nd∶GdVO4/Cr4+∶YAG/KTP and Nd∶YAG/ Cr4+∶YAG/LBO intracavity frequency doubling passively Q-switched green laser are simulated through numerical solution.After the comparison with the experimental data,the theoretical analysis accords with the experimental results,it proves that the rate equation is universally applicable to the intracavity frequency doubling passively Q-switched green laser.The results obtained have guiding significance and reference value to the parameter design and optimization of these devices. |
