Abstract

We demonstrate a new technique for noise suppression that uses differential detection of the transmission of a linearly- and a circularly polarized beams propagating through different parts of a single rubidium vapor cell filled with a buffer gas mixture. The common-mode noise, associated with the laser frequency and amplitude noise, is suppressed by the differential detection of the two parts of the laser beam. The technique is simple and applicable in compact and chip-scale devices.
