Abstract
Cold atomic source was first introduced into the community of precursor in 2006, when Jeong (Phys. Rev. Lett. 96:143901, 2006) reported the direct observation in a cloud of potassium cold atoms. Later, Wei et al. reported observation in a 2-dimensional magneto-optical trap with optical depth as high as 50, with the assistance of EIT effect. With the advent of cold atom traps and tunable diode lasers, we now have a single physical system with parameters that can be widely tuned to cover both physical regimes. Also, in the chapter, we discuss and interpret the slow and fast light phenomena while comparing with the precursor propagation in the same system. In the last section, we review the stacked precursors measured with a multiple-step function.
