摘要
The conditions necessary to implement a single-photon pulse source using quantum filtering based on the coherent population trapping phenomenon in N-systems of atomic levels are determined. The dependences of dark resonance characteristics on laser field intensities are experimentally measured in Rb vapor. These dependences define optimum intensity ratios and pulse durations of used laser beams, at which the system can efficiently operate as a single-photon quantum filter.
