摘要
本文报道二步共振激发钙原子产生250～400nm波段内一系列紫外辐射的研究结果,分析了辐射产生的机制,确认部分辐射由四波混频过程产生,部分辐射是起始于高三重态的受激辐射,并讨论了高三重态的布居机制.
This paper reports the research results of UV emission within 250-400nm based on the two-step resonant excitation of Ca atomic system. The generating mechanism of UV emission is analyzed. It is determined that part of these UV emission lines are generated by four-wave mixing processes, the others are due to stimulated emission from high-lying triples-states. The distribution processes of highlying triples-states are also discussed.
