Time-resolved detection of relative intensity squeezed nanosecond pulses in a 87Rb vapor

In this talk, we demonstrate a system capable of producing pulsed squeezed light via four-wave mixing in a rubidium vapor. By employing a pulsed input, 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, 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.
