We reported the formation of diffraction ring patterns induced by transmitted Gaussian laser beam through 8-hydroxyquinolin-l-ium 4-aminobenzenesulfonate(8HQABS)solution as absorbing medium.Theoretical model de-pending on the Fresnel-Kirchhoff diffraction(FKD)theory was used to generate diffraction rings with respect to the sample position.Analysis of the generated diffraction rings shows a reasonable agreement between the features of the experimental and numerical diffraction rings.Our results are considered to be useful to understand the way of propa-gation and interaction of laser beam with liquid absorbing medium.
