    "abstract": "We propose a novel method enabling to create a high-contrast dark resonance\nin the 87Rb vapor D2-line. The method is based on an optical pumping of atoms\ninto the working states by a two-frequency, linearly-polarized laser radiation\npropagating perpendicularly to the probe field. This new scheme is compared to\nthe traditional scheme involving the circularly-polarized probe beam only, and\nsignificant improvement of the dark resonance parameters is found. Qualitative\nconsiderations are confirmed by numerical calculations.",
