Abstract
We present a new approach based on gene expression programming (GEP) for modeling of the laser-guided atom flux of rubidium. The GEP has been running based on experimental data of the atom flux (guided atom signal) versus laser detuning from resonance (ranging from -50 GHz to 20 GHz) as well as the laser intensity to produce the corresponding atom flux. Two different GEP models are developed to generate two mathematical equations. In the GEP model 1, the laser detuning from resonance and the laser intensity have been used as input variables. In the GEP model 2, the radius of curvature of the optical fiber, through which the atoms are guided, and the laser intensity are used as input variables. The experimental, calculated and predicted atom flux are compared. The obtained functions show a good match to the experimental data. The results are promising that the proposed GEP models can be used in the prediction of the laser-guided atom flux in hollow-core optical fibers.
