Electromagnetically induced transparency in a Zeeman-sublevels Λ -system of cold 87 Rb atoms in free space
Xiaojun Jiang, Haichao Zhang, Yuzhu Wang
We report the experimental investigation of electromagnetically induced transparency (EIT) in a Zeeman-sublevels Λ -type system of cold 87 Rb atoms in free space. We use the Zeeman substates of the hyperfine energy states 5 2 S 1/2 , F = 2 and 5 2 P 3/2 , F ' = 2 of 87 Rb D 2 line to form a Λ -type EIT scheme. The EIT signal is obtained by scanning the probe light over 1 MHz in 4 ms with an 80 MHz arbitrary waveform generator. More than 97% transparency and 100 kHz EIT window are observed. This EIT scheme is suited for an application of pulsed coherent storage atom clock (Yan B, et al. 2009 Phys. Rev. A 79 063820).
