Abstract

Recent experiments have shown that second and third harmonics generated in laser plasmas on solid surfaces preserve the polarization of the incoming laser beam. This contradicts to most theories according to that the polarization of even harmonics should be p-polarized for p- and s-polarized laser beams as well. In the present work a theoretical model of harmonic generation at surfaces having large density gradient is developed, and applied to explain the experimentally observed polarization dependence of the harmonics on that of the fundamental beam.
