Effect of Surface Nonlinearity Distribution on Second Harmonic Generation under Tightly Focused Beams

Effect of Surface Nonlinearity Distribution on Second Harmonic Generation under Tightly Focused Beams

A thorough integral formulation describing the second harmonic generation under tightly focused linearly and radially polarized beams for an arbitrary distribution of the nonlinear susceptibility over the surface of isotropic media was presented. We numerically simulated effects caused by the straig...
