The Doppler effect of moving atoms can create irreversibility of light. Weshow that the laser field in electromagnetic induced transparency (EIT) schemewith atomic motion can control the directional propagation of twocounter-propagating probe fields in atomic gas cell. The quantum coherenceeffect serves as an optical transistor. Interference of the two output fieldsfrom the cell shows useful feature for determining the mean atomic velocity andcan be useful as quantum velocimeter. We also find that the sign of thedispersive phase in EIT has a unique property, which helps to explain certainfeatures in the interference.
