摘　　要：介绍了两种Nd∶YAG倍频的方法 :折叠腔腔内倍频和腔外环形腔倍频 ,并着重对腔外环形腔倍频进行了研究 ,这种方法在 1kHz调QNd∶YAG激光 5 0W平均功率输入的情况下 ,获得了 1 7 5W平均功率的绿光输出 ,光 光转换效率达 35 % ,较好地解决了激光微细聚焦问题 。Two kinds of frequency doubling methods by using KTP crystal are introduced. The first is frequency doubling in a folded cavity, and the second is achievement of second harmonic generation in a resonant ring cavity. In the latter method, using an 1 kHz Q switched Nd∶YAG laser with an average power of 50 W as the input light, a green light with average power of 17.5 W and harmonic conversion efficiency of 35% is obtained. The laser used for mini focus of laser rapid prototyping is demonstrated.
