摘要
采用入射光与谐振腔模式失配的方法利用模式转换腔将基模高斯光束转换成高阶厄米高斯模；基于不同阶模式对应的共振腔长非简并和输出幅度非简并的特性，设计了一种用于光学模式转换腔模式自动搜寻与锁定伺服系统，在实验上获得了稳定的厄米高斯模TEM00，TEM10和TEM20。
Abstract
High-order Hermite-Gauss modes are transformed from fundamental Gauss mode using mode converter cavity by mode-mismatching technique between input beam and cavity. Based on the nondegeneration of resonant cavity lengths and output amplitudes of different order Hermite-Gauss modes, an auto-searching and auto-locking servo system of cavity for high-order mode generation is realized and stable Hermite-Gauss modes of TEM00, TEM10 and TEM20 are obtained experimentally.
