New spatial phase filters matched to transverse modes were proposed and investigated;
they were analogs of sinusoidal phase diffraction gratings with a variable modulation depth.
A set of spatial phase filters matched to Gauss–Laguerre modes was made and studied
experimentally. The energy efficiency of the phase niters was 7–10 times higher than that of
amplitude niters.
Abstract
New spatial phase filters matched to transverse modes were proposed and investigated; they were analogs of sinusoidal phase diffraction gratings with a variable modulation depth. A set of spatial phase filters matched to Gauss–Laguerre modes was made and studied experimentally. The energy efficiency of the phase niters was 7–10 times higher than that of amplitude niters.
