【摘要】 在连续钛宝石环形激光腔中，无光学单向器时存在相向传播的两束光波，有两个对应的输出光束。用平面镜反馈回其中一束，可实现环形腔的行波激光运转。本文给出了该结构钛宝石激光器的输入一输出关系、双向波功率比随泵浦功率和输出耦合率的变化、外腔棱镜调谐特性，以及腔内插入标准具进行线宽压窄的实验结果。更多还原

【Abstract】 For a CW Ti: sapphire rins laser without optical diode, there are two output beams corresponding to two oppositely traveling waves in the cavity. Unidirectional operation is obtained when one of the output beams is reflected back into the cavity. In this paper, the experimental results of an unidirectional operation laser, includins input-output curve, the power ratio of the two oppositely travelins waves under different coupler transittunces and pump levels, the tuning characteristics with a prism in the external cavity, and the narrowing of the output spectrum with etalons, are given.更多还原
