Light Shift Measurements in a Cesium Fountain without the use of Mechanical Shutters

Abstract

We present measurement confirming operation of a cesium fountain frequency standard with light shift below 10-(15) (and with evidence suggesting it is several orders of magnitude below this level) but without the use of mechanical shutters. Suppression of the light shift is realized using a master-slave laser configuration by reducing the overall optical a power delivered to the physics package as well as spoiling the injection of the slave, causing it to lase far off resonance (1-2 nm) as proposed by the authors several years ago.
