2020年12月1日 · An electron scattering scheme is proposed to explore and quantify the focal field of radially polarized beam (RPB). Based on the Richard–Wolf method we deduce the …

2016年12月8日 · Abstract: We report an all-fiber laser that emits a radially polarized cylindrical vector beam (CVB) at 1 μm based on an intracavity acousto-optic mode converter. We …

phase distribution is crucially important for any kind of cylindrical vector beam. In the measurement the phase distribution of vectorial optical beams such as the RPBs, the most …

2020年9月15日 · Due to the polarization pattern aligned along the radial direction, radially polarized beam (RPB) has unique focusing features with a dominant longitudinal component …

A beam with purely longitudinal chirality on the optical axis is the azimuthally-radially polarized beam (ARPB) [31], a superposition of an azimuthally polarized beam (APB) [35], [36], [37], …

2022年4月25日 · : In this study, an analytical formula for the self-focusing length of a radially polarized beam (RPB) is first derived, which has a similar behavior to the semi-empirical …

2011年1月11日 · On 1/9/21 construction crews installed this 84-foot steel beam across four Red and Purple Line tracks to support the new Red-Purple Bypass north of Belmont. When the …

2011年12月28日 · (57) A surveying system comprises a plurality of rotary laser devices (1a, 1b), being installed at known points, for projecting laser beams (3a, 3b) in rotary irradiation and for …

We simulate the focal intensity distribution of a radially polarized beam, in view of the vector diffraction theory. We summarize two important rules: (i) the marginal ray of the aperture...

2017年10月30日 · In this paper, the general formula for tightly focusing radially polarized beams (RPB) superposed with off-axis vortex arrays is derived based on Richard-Wolf vector …
