角锥棱镜阵列谐振腔输出模式研究
Study on output modes of a corner cube array resonator
摘要
Abstract
In order to study the output characteristics of a corner cube array resonator, the resonator was constructed with a corner cube array ( CCA) and a planar mirror as rear mirror and output mirror respectively. Its near-field and far-field mode distribution was demonstrated through numerical simulation. The coherent output of the resonator was theoretically analyzed. Furthermore, the mode distribution of a Nd: glass laser with this type of resonator was obtained in experiments. The results show that the simulated mode distribution agrees with the experimental results. The profile of the near-field mode distribution is hexagonal and similar to the geometry of the CCA. There is a high pulse in the middle of the far-field beam spot with many low pulses around it. The quantity and layout of the pulses in each circle are the same as those of the corresponding corner cubes in the CCA. The results also show that it' s feasible to achieve coherent laser output with a corner cube array resonator.关键词
