摘要：

Characteristics of laser trapping of Ca and Sr are experimentally studied and discussed. The lifetime of the trap is found to be limited by accumulation of the population in the P-3(2) state, not by the decay P-1(1) --> D-1(2). This result allows us to generate a continuous free-falling flow of ultra-cold ground state atoms which is useful for ultra-high resolution spectroscopy. Effects of an optical pumping laser which recycles the D-1(2) population in Sr are investigated.
