摘　　要：本文从速率方程出发，通过最大化峰值功率，研究了调Ｑ激光器的最佳化问题，给出了一定泵浦水平下，使峰值功率最大的最佳的输出耦合镜反射率的数值解。根据所述原理，对一个多模的Ｎｄ∶ＹＡＧ调Ｑ激光器进行了最佳化的实验研究。结果表明，该优化理论使具有高增益损耗比的调Ｑ激光器的峰值功率比传统方法提高１０％。We investigate the optimization of Q switched lasers by means of maximum peak power using the rate equations.In this work,we presents numerically calculated of output mirror reflectivity which optimize the peak power of actively Q switched lasers for a given pump level.Meanwhile,according to the optimization theory,a Nd∶YAG Q switched laser is studied experimentally and the maximum peak power increases about 10% than Degnans method loss ratio laser design tradeoffs.
