摘要
分析了束变换环孔激光谐振腔的特点和优势,给出了这种复杂激光谐振腔的设计原理。对采用该方法设计的激光谐振腔空腔模式进行了计算和分析,并使用自行编写的三维光线追迹程序对这种腔的稳定性也进行了研究,结果表明这种谐振腔输出光场分布合理,相位均匀,远场分布接近衍射极限,并且这种腔对于扰动在一定范围内具有抑制能力,是一种研究价值很高的非稳腔。此外针对该腔提出的设计及模式计算方法对其他复杂腔型也具有一定的参考价值。
Abstract
A design method of beam-converting annular resonator is presented. And the bare cavity modes of this resonator are calculated, the advantages of beam-converting annular resonator are analysed. The cavity′s stability is also studied with home-made three-dimensional ray tracking program. It showed that beam-converting aannular resonator is a valuable resonator with high extraction effiecency and near-diffractive-limit optical quality, and can sustain certain disturbance. The methods presented are also valuable to the design and calculation of other complex laser resonators.
