Experimental generation of Hermite-Gauss and Ince-Gauss beams through kinoform phase holograms

摘要

We generate Hermite-Gauss and Ince-Gauss beams by using kinoform phase holograms encoded onto a liquid-crystal display. The phase transmittance of this holograms coincide with the phases of such beams. Scale versions of the desired beams appear at the Fourier domain of the KPHs. When an appropriated pupil size is employed, the method synthesizes HG and IG beams with relatively high accuracy and high efficiency. It is noted that experimental and numerical results are agreement with the theory.
