Abstract:
The paper considers paraxial Gaussian laser beams with different polarization states and their characteristics, such as the Poynting vector, gradient force, and force density, which are important for evaluating the effects of radiation on matter. An analysis of the considered characteristics of laser radiation from the point of view of the formation of photoinduced microrelief in an azopolymer film is carried out.

Keywords:
Gaussian beam, polarization state, optical forces, optical recording of materials, azopolymer, azochromophore, photoisomerization, photomigration, surface microstructures.
