摘　　要：利用角锥棱镜阵列作为谐振腔的后腔镜,设计了一种新型的钕玻璃激光器谐振腔并进行了实验研究。实验中获得了能量大于500 J的1.06μm激光脉冲,发散角0.6 mrad左右,电光效率为2.3%。实验采集到的输出光斑不是一系列强度相差不大的子脉冲,而是中间有一个强峰,周围分布着一系列强度小得多的次峰。最后,对实验结果进行了解释与讨论,提出了利用角锥棱镜阵列进行光束相干合成的设想。A new type of Nd：Glass laser resonator was designed and demonstrated. With the corner cube array as the cavity back-end-mirror, the Nd：glass laser outputs 1.06 μm high energy laser pulse. The pulse energy is more than 500 J, the beam divergence angle is about 0.6 mrad, and the electro-optic efficiency is 2.3%. The output beam spot is not a series of approximate same-amplitude sub-pulses, but a high pulse in the middle with many lower pulses around it. Lastly, the experimental results are explained and discussed. The idea of beam coherent combination using the corner cube array resonator is put forward.
