ON THE DIFFRACTION OF PARTIALLY COHERENT LIGHT

The diffraction of partially coherent light at a narrow slit is calculated for a given coherence function satisfying the wave equation at all points. It is shown that the divergence angle depends only on the wavelength and the coherence interval but not on the diameter of the end face. Since the div...

Description
Summary:The diffraction of partially coherent light at a narrow slit is calculated for a given coherence function satisfying the wave equation at all points. It is shown that the divergence angle depends only on the wavelength and the coherence interval but not on the diameter of the end face. Since the divergence angle and coherence interval are uniquely related, and each can be obtained independently, a direct experimental check of the relation between the two is possible. Applicability of the results to describe the radiation from a dielectric resonator, e. g., a ruby laser, is discussed. (Author) Trans. of Akademiya Navuk BSSR, Minsk. Doklady, v8 n7 p438-40 1964.
