摘　　要：理论上分析了钙离子红外自终止激光和紫外复合激光存在同时振荡的可能性 ,通过改进实验装置 ,首次获得钙离子的红外和紫外激光的同时振荡 ,二束激光输出总平均功率约 70mW ,其中红外和紫外激光约各占一半。比较了不同谐振腔对激光输出特性的影响 ,测量并分析了激励电脉冲与所产生二束激光脉冲波形的关系。The simultaneous oscillations of calcium ion recombination and self-terminating laser were analysed theoretically and obtained in the experiment for the first time through improving discharge circuit and cavity structure. The maximum average output power reaches 70 mW. The photoelectric pulse waveforms were measured and discussed. In order to make the electron temperature decrease quickly, helium is used as buffer gas. Laser is produced by pulse discharge, so that there is no second harmonic generation.
