A comparison of the dependence of saturated absorption signals on pump beam diameter and intensity
Geol Moon, Heung‐Ryoul Noh
We studied the nonstationary phenomena for the saturated absorption spectra peaks of the 87Rb D2 line by varying the diameter and the intensity of a pump laser beam. We found that the dependence of the magnitude of the signals on the variation of the beam diameter was almost equivalent to that of the pump beam intensity both experimentally and theoretically. However, we observed that the signals for the cycling transition line Fg=2→Fe=3 were different from each other, which could be explained by the saturation effect. We compared the experimental results with theoretical calculations based on the rate equation model. We observed good agreement between them.
