Abstract:

We calculate the fluorescence and nonlinear absorption spectra of alkali-metal atomic vapor in ultrathin cells. We obtain closed-form equations for the nonlinear atomic polarization by applying perturbation theory to the intensity of linearly polarized laser light for arbitrary values of the total momenta of the resonant levels. The results of this calculation are consistent with experimental data obtained using an ultrathin cell filled with Cs133 vapor.

Keywords:

thin atomic alkali-metal vapor, ultrathin cell, nonlinear atomic polarization, absorption and fluorescence coefficients
