| 摘 要： | This paper has observed linewidth narrowing of dark states in rubidium cell by using the Hanle configuration. The reduction of the coherent resonance width under the transition of ^87Rb Fg = 1 → Fe = 0 is observed and the qualitative explanation about its mechanism is presented. Multiple subnatural width dips are obtained with a linearly polarized laser beam for the transitions of ^87Rb Fg = 1→Fe = 0, 1, 2. The feature of negative and positive slope, namely dispersionlike feature, is observed in the transmitted light.

| Abstract: | This paper has observed linewidth narrowing of dark states in
rubidium cell by using the Hanle configuration. The reduction of the
coherent resonance width under the transition of 87Rb
Fg=1\rightarrow Fe=0 is observed and the qualitative
explanation about its mechanism is presented. Multiple subnatural
width dips are obtained with a linearly polarized laser beam for the
transitions of 87Rb
Fg=1\rightarrow Fe=0, 1, 2.
The feature of negative and positive slope, namely dispersionlike
feature, is observed in the transmitted light. |
