Collinear diffraction of divergent optical beams

Department of Physics, M.V. Lomonosov Moscow State University, 119992 Moscow, Russia

Abstract

Two variants of anisotropic collinear diffraction of light on a sinusoidal diffraction grating are studied theoretically with forth and back light scattering relative to the direction of the incident beam. For both variants, two-dimensional transfer functions are calculated and their modification with optical wavelength and diffraction grating period is analyzed. The dependence of integral diffraction efficiency and filter passband on optical beam divergence is examined.
