Abstract
The paper considers photo-induced microrelief formation using Gaussian paraxial vortex laser beams with different polarizations and their characteristics, such as the Poynting vector, gradient force and force density, which are important for assessing the effect of radiation on matter. It is shown that the characteristics, which depend only on the intensity gradient, do not allow to correctly describe dependence of the distribution of optical forces and the formed relief. A model taking into account non-gradient forces is presented. Theoretical and experimental results are compared.
