Abstract

Squeezed light is a valuable resource in the fields of continuous-variable quantum information, quantum communication, and quantum optics [1]. In this talk, we demonstrate a system capable of producing pulsed squeezed light via four-wave mixing in a rubidium vapor [2]. By employing a pulsed input [3], we produce nanosecond relative-intensity squeezed pulses and employ time-resolved detection to measure the degree of squeezing obtained. With respect to recent noise-spectrum squeezing experiments in atomic vapors [2], the present work is based on time-domain detection. The basic idea behind the generation of relative-intensity squeezed light as presented in this work relies on off-resonant four-wave mixing in a double lambda-system [2]. A strong pump, ωp, interacts with a pulsed probe beam, ωs, which is offset from the pump by approximately the hyperfine ground state separation. Under suitable conditions, this energy level structure allows for the parametric amplification of the probe beam while simultaneously creating its quantum-correlated conjugate.
