An abnormal phenomenon in the saturated absorption spectrum of 87Rb

摘要

A polarization-type saturated absorption spectrum set-up for 87Rb atom laser cooling and trapping has been established in our laboratory. By changing the polarization components and optical power, enhanced absorption of the transition 5S1/2 F=2 → 5P3/2 F'=3 was observed with other transitions and cross-over resonance staying unvaried.
