We have theoretically studied the pulsed regime of electromagnetically induced transparency. In particular, simulations of propagation of Gaussian and $0\ensuremath{\pi}$ copropagating laser pulses in a medium consisting of three-level $\ensuremath{\Lambda}$ atoms have been performed. It has been found that even at the two-photon resonance, the length of propagation for the $0\ensuremath{\pi}$ pulses is much smaller than the one for the Gaussian probe pulses. Using the dark and bright basis, we explain this behavior. Some possible applications are discussed.
