We investigate whether it is possible to store and retrieve the intense probepulse from a $\Lambda$-type homogeneous medium of cold atoms. Through numericalsimulations we show that it is possible to store and retrieve the probe pulsewhich are not necessarily weak. As the intensity of the probe pulse increases,the retrieved pulse remains a replica of the original pulse, however there isoverall broadening and loss of the intensity. These effects can be understoodin terms of the dependence of absorption on the intensity of the probe. Weinclude the dynamics of the control field, which becomes especially importantas the intensity of the probe pulse increases. We use the theory of adiabatons[Grobe {\it et al.} Phys. Rev. Lett. {\bf 73}, 3183 (1994)] to understand thestorage and retrieval of light pulses at moderate powers.
