Geometric spin hall effect for Gaussian beam

We report the results of experimental observation of the influence of light polarization on its propagation in free space (Geometric spin Hall effect of light) for the whole Gauss beam under new experimental condition. We experimentally confirm the existence of the effect of the focal waist shift under the change of the sign of the circular polarization of light passed through the upper (or lower) half of a lens. Computer methods of image processing have allowed to obtain the shift value 3,0 ± 0,5 µm.
