ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ ФОКУСИРОВКИ НЕОДНОРОДНО ПОЛЯРИЗОВАННЫХ ПУЧКОВ, СФОРМИРОВАННЫХ ПРИ ПОМОЩИ СЕКТОРНЫХ ПЛАСТИНОК
2014
Experimentally investigated a focusing of inhomogeneously polarized laser beams formed by the sector polarizing plates. The analysis of noise distortion beams formed different types of plates is performed. Focusing is implemented by a micro-objective with high numerical aperture and by a diffraction axicon with moderate numerical aperture . It's experimentally shown that beam distortion by noise have a little effect on the intensity distribution in the center of the focus area due to its high frequency nature. It is in agreement with the simulation results.
