We show how two circular polarization components of a linearly polarized pulse, propagating through a coherently driven dilute atomic vapor, can be well resolved in a time domain by weak measurement. The slower group velocity of one of the components due to electromagnetically induced transparency leads to a differential group delay between the two components. For a low number density, this delay may not be large enough to temporally resolve the two components. We show how this can be enhanced in terms of the mean time of arrival of the output pulse through a postselected polarizer. We demonstrate the idea with all the analytical and numerical results, with a specific example of alkali atoms.
