We investigate the storage and retrieval of a weak signal light in a thermal Λ type three-level atomic system. We examine in detail the time-dependent aspect of this system in which atomic motion with both internal and translational degrees of freedom is taken into consideration under different conditions of the atomic momentum distributions and the settings of two light fields. We confirm the effectiveness of a Doppler-free copropagating configuration in promoting the efficiency of the system operation.
