Show affiliationsWe study theoretically the formation of a double radio-optical resonance (DROR) in 87Rb vapour in a cell with an anti-relaxation coating. We develop a quantum-kinetic approach to the study of the Dicke narrowing. We examine various DROR schemes for different polarizations of the laser radiation. We find that the short-term stability σy of a DROR-based frequency standard improves significantly (by an order of magnitude) if a laser with a broad spectrum is used, in comparison to the case of excitation by a narrow-band laser radiation, and reaches ultimately the value σy ~ 1 × 10−14 τ−1/2, where τ is the integration time (in seconds).
