Abstract
The properties of phase retarders for high-power laser irradiation based on metallic diffraction gratings with various profile parameters are investigated both theoretically and experimentally. High energy efficiency of linear-polarized light transformation into the elliptically-polarized specular-reflected wave is achieved at the resonance excitation of surface electromagnetic waves. The nonselective phase retarders on the base of `deep' gratings for various wavelengths and shift values were also designed, and effectivity of their application for metal cutting with high-power CO2-lasers was demonstrated.
