Influence of Pump Lights Duty Cycle on Cesium Atomic Magnetometer
Recently,atomic magnetometers have been researched widely for its ultra high sensitivity.But the influence of pump lights duty cycle on atomic magnetometers has been concerned little.In this paper,wc described a sensitive cesium atomic magnetometer based on circular dichroism,which had the advantage of easily locking the probing laser to the necessary frequency.We experimentally investigated the amplitudes and linewidths of magnetic resonance signals at different modulated duty cycle of the pump light.The result indicated that our magnetometer achieved the highest sensitivity at the duty cycle of 30%.Its valuable for optimizing the sensitivity of most atomic magnetometers.
