title: Vacuum squeezed light for atomic memories at the D2 cesium line.
abstract: We report the experimental generation of squeezed light at 852 nm, locked on the Cesium D(2) line. 50% of noise reduction down to 50 kHz has been obtained with a doubly resonant optical parametric oscillator operating below threshold, using a periodically-poled KTP crystal. This light is directly utilizable with Cesium atomic ensembles for quantum networking applications.
