耦合腔结构可调谐双频固体激光器的研究
Tunable Two-Frequency Solid-State Laser with Coupled-Cavity Configuration
摘要
研究了一种激光二极管(LD)抽运的频差可调谐双频固体激光器，对耦合腔实现双频的方法进行了分析。实验中使用输入镜与腔内插入标准具形成耦合腔实现单频运转，双λ/4波片使单纵模激光频率分裂，通过改变两个λ/4波片快轴之间的夹角来实现频差调谐。在LD抽运光功率为290 mW的条件下，获得了频差在0~1.1 GHz范围内可调、功率为34 mW的双频激光输出。
Abstract
A laser-diode-pumped two-frequency solid-state laser with tunable frequency difference is investigated, the principle of coupled-cavity is presented. Single-longitudinal mode oscillation is obtained from a coupled-cavity setup. Two quarter-wave plates are inserted to lift the degeneration of frequencies in orthogonal polarizations. 34 mW output power of two-frequency laser with tunable frequency difference is achieved. The beat note frequency can be continuously tuned from 0 to 1.1 GHz.
