Acousto-optic modulators in Raman-Nath diffraction regime as phase modulators in modulation transfer spectroscopy

Abstract

AOM-RN, a compact acousto-optic modulator operating purely in the Raman-Nath diffraction regime, extended the tools employed in laser spectroscopy as optical phase modulators. We report the AOM-RN capacity to be employed as phase modulator in pump-probe modulation transfer spectroscopy in atomic vapors.
