| 摘 要： | 双光子吸收碱金属蒸汽激光器（TPAL）在基础研究和国防工程中有重要的应用前景，近些年来已成为激光领域研究热点之一，但TPAL还缺少相关的理论模型。因此，本文基于碱金属原子的双光子吸收能级跃迁过程构建速率方程，并建立了TPAL理论模型，研究了单波长泵浦双光子吸收铷蒸汽激光器（Rb-TPAL）的工作特性，分析了泵浦光束腰位置、蒸汽池温度以及泵浦功率对Rb-TPAL蓝光输出特性的影响。结果表明，通过优化泵浦光束腰位置和蒸汽池温度，在高功率泵浦情况下，Rb-TPAL可获得高功率蓝光激光输出。

| Abstract: | Two-photon absorbing alkali vapor laser (TPAL) has important application prospects in basic research and defense engineering, and has become one of the research hotspots in the laser field in recent years. However, TPAL still lacks relevant theoretical models. The operating characteristics of a single-wavelength pumped two-photon absorbing rubidium vapor laser (Rb-TPAL) are investigated, and the effects of pump beam waist position, vapor cell temperature and pump power on the blue light output characteristics of Rb-TPAL are analyzed. The results show that the optimal pump beam waist position and vapor cell temperature exist for the Rb-TPAL to output the highest power blue laser. By optimizing the pump beam waist position and vapor cell temperature, the Rb-TPAL can obtain high power blue laser output under high power pumping. |
