Durham大学,Rochester大楼,南路,Durham DH1 3LE,英国,Durham大学物理系,我们从理论和实验上研究了激发态原子在低态被相干泵浦的热蒸汽中的吸收。我们发现,跃迁线宽可以是亚自然的,即小于下态和上态的总和。对于6P的特定情况
Department of Physics, Durham University, Rochester Building, South Road, Durham DH1 3LE, UKWe investigate, theoretically and experimentally, absorption on an excited-state atomic transi-tion in a thermal vapor where the lower state is coherently pumped. We nd that the transitionlinewidth can be sub-natural, i.e. less than the combined linewidth of the lower and upper state.For the speci c case of the 6P
