文摘

We studied the Bragg-matching characteristics of atomic coherence gratings recorded in a coherently driven solid based on electromagnetically induced transparency by using a confocal scheme. The results show that the atomic coherence grating is of the same holographic properties as a traditional thick volume holographic grating. Such Bragg-matching characteristics of atomic coherence gratings would lead to important potential applications in optical signal processing and memory based on quantum coherent media.
