This work presents a simple approach for determining the contribution of Lorentzian or Gaussian statistics by data fitting the spectrum to a Voigt profile. The fitting result shows that the Lorentzian width remains almost constant (∼1.51MHz) and the Gaussian width increases (∼1.0–2.0MHz) while changing the laser intensity or atomic density. The frequency shift associated with the cesium 6S–8S two-photon...
The light shift and linewidth of cesium 6S-8S two-photon transitions are measured in the system. The light shift is -8.60 Hz/(mW/mm2) which is in good agreement with theoretical result. The linewidth is about 1.51 MHz.
