The efficiency of an ensemble-based optical quantum memory depends criticallyon the strength of the atom-light coupling. An optical cavity is an effectivemethod to enhance atom-light coupling strength, with the drawback that cavitiescan be difficult to integrate into a memory setup. In this work we showcoherent enhancement of atom-light coupling via an interference effect. Thelight to be absorbed into the atomic ensemble is split and used to drive theatoms from opposite ends of the ensemble. We compare this method theoreticallyto a cavity enhanced scheme and present experimental results for our coherentenhancement in cold rubidium-87 atoms that show an efficiency of $72\pm5\%$ anda storage lifetime of $110\pm 10$ us.
