摘要
采用2400 l/mm的平面光栅搭建Littrow外腔压窄半导体激光器输出激光线宽,获得中心波长可调的线宽0.16 nm的半导体激光作为铷蒸气激光的泵浦源。实验中,使用斩波器将泵浦光变为脉宽1 ms,重复频率100 Hz的重复脉冲形式,聚焦进长度为8 mm的铷蒸气泡,泡内充入79 kPa甲烷作为缓冲气体。进入铷蒸气泡的泵浦光峰值功率为1.84 W时,控制铷泡温度在125 ℃,获得了峰值功率17.5 mW的基模线偏振铷激光输出。
Abstract
Based on the research internal and overseas, the principle of the excimer pumped alkali laser (XPAL) is explained, and the advantages and disadvantages of the XPAL are analyzed. Taking into consideration the difficulties that the diode pumped alkali laser (DPAL) meets on its development, the ability to solve or avoid these difficulties of XPAL is also analyzed. By summing up the achievements of the XPAL, the possible further prospect is proposed. The XPAL is of possibility to improve the performance of the DPAL.
