通过对种子注入调谐光参量振荡激光器的理论计算．从理论上证明了种子注入法不仅能压窄参量激光的线宽，还能降低参量振荡激光器振荡的阈值．增大其输出参量激光的能量．提高输出激光能量的转换效率．并在实验上给予证明。 Theoretical Calculation of Tuning Optical Parametric Oscillation Lasers by Implantation of Seeds. It is theoretically proved that the seed injection method can not only narrow the linewidth of the parametric laser but also reduce the threshold of oscillation of the parametric oscillating laser. Increase its output parameter laser energy. Improve output laser energy conversion efficiency. And in the experiment to prove.
