摘　　要：We report the experimental investigation of electromagnetically induced transparency （EIT） in a Zeeman-sublevels A-type system of cold 87Rb atoms in free space. We use the Zeeman substates of the hyperfine energy states 52 S 1/2, F =- 2 and 52P3/2, F1 = 2 of 87Rb D2 line to form a A-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）.We report the experimental investigation of electromagnetically induced transparency （EIT） in a Zeeman-sublevels A-type system of cold 87Rb atoms in free space.
