Diffraction efficiency of reflection gratings with a parabolic section profile.
Diffraction properties of reflection gratings with a parabolic groove profile are analyzed. It is shown that these structures produce a large number of diffracted waves with similar intensities. Theoretical and experimental results at the wavelength of 780 nm are shown. These gratings are made from holographic diffraction gratings recorded in a photoresist.
