The non-paraxial and vectorial effects have an important role in the dynamics of highly confined beam. In this paper, the vectorial non-paraxial propagation of Gaussian field in the saturable absorber media and its dependence on the polarization and characteristics of incident Gaussian field are investigated numerically. In the optimal regimes for nanolithography, the mutual coupling between components of optical field and mode coupling between different orders of Hermite-Gaussian mode lead to generation of various patterns upon propagation through saturable absorber media. The vectorial effect is responsible for the symmetry breaking.
Keywords: Vectorial nonparaxial propagation, Saturable absorber, nanolithography
