基于国内外相关研究成果,对准分子宽带泵浦碱金属激光器(XPAL)的原理进行了阐述，对其优缺点进行了分析，针对半导体泵浦碱金属蒸气激光器(DPAL)发展中所面临的困难，分析了XPAL解决这些困难的潜力。最后综述了XPAL近年的发展，提出了下一步的发展方向。

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.
