【摘要】 提出了一种用于激光陀螺仪的LD泵浦Nd∶YVO4双向输出固体环形激光器。计算了谐振腔的环绕矩阵,分析了曲面镜焦距和放置距离对谐振腔稳定性的影响。得出了构成环形腔的稳定条件,光腰最大化条件,以及光束特性。并对所设计的环形腔进行了实验,获得了双向、多纵模基横模连续输出。更多还原

【Abstract】 A diode-pumped Nd∶YVO₄ bidirectional solid-state ring laser used for optical gyro is discussed. By exploiting ABCD transmission matrix theory, the influence on cavities’ stability by the ROC and separation distance of curved mirrors and cavities’ length is analyzed. Stability region of the cavity and maximum beam waist plot are shown as well as Gauss beam characteristics. In the experiment, the bidirectional, multi-longitudinal and TEM00 mode continuous wave outputs are obtained.更多还原
