Abstract: We report a quantum optical storage time-extended near perfect photon echoprotocol using a phase locking method via an auxiliary spin state, where thephase locking acts as a conditional stopper of the rephasing process resultingin extension of storage time determined by the spin dephasing process. The nearperfect retrieval efficiency is owing to phase conjugate scheme, which givesthe important benefit of aberration corrections when dealing with quantumimages.
