title: Research of far-field diffraction intensity pattern in hot atomic Rb sample.
abstract: In this work we present a study of the far-field diffraction intensity patterns in the Rb atomic medium. It is found that the far-field diffraction intensity patterns are intimately related to the incident frequency, power, the atomic number density and the position of the sample. The results demonstrate that the far-field diffraction intensity patterns can sensitively reflect the nonlinear optical properties of the medium. The information obtained is of meaning in the application fields, such as the nonlinearity of the medium measuring, optical limiting.
