Abstract

The formation of rf-dressed Rydberg dark states in thermal Rb vapour is demonstrated. It is shown that such states exhibit enhanced sensitivity to dc electric fields compared to their bare counterparts and enable precise measurement of the dc field independent of laser frequency fluctuations.
