Phase relief gratings with conic section profile used in the production of multiple beams.
We analysed the diffraction properties of phase relief gratings with conic and quasiconic section profiles and showed their interesting properties as efficient multiple beam splitters. Optimization of their characteristics was studied for seven and thirteen beams. We compared theoretical calculations with experimental results using quasiconic section profile gratings produced on photoresist.
