High-contrast dark resonance in σ+ - σ- optical field

The amplitude of Λ resonance in alkali atoms is limited by perturbing cycling transitions in the case of D2 line or by existence of additional trapping states in the case of D1 line. We propose to eliminate these extra trapping states by using two counter‐propagating bichromatic fields of orthogonal...
