| Abstract: | 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. |
