WebbFocusing shift of Bessel-Gauss (BG) beam with radial varying polarization is investigated by vector diffraction theory in this article. The radial phase modulation is given by a function of radial direction angle θ and m. It was found that the focal shift only can be altered considerably by the phase modulation parameter m, and the focus region intensity shape … WebbThe article was published on 2024-09-03.

WebbWe propose an optical tweezers setup based on an annular-shaped laser beam that is efficient to trap 2.8 μ m-diameter superparamagnetic particles. The optical trapping of such particles was fully characterized, and a direct absolute comparison with a geometrical optics model was performed. With this comparison, we were able to show that light … name dim is not definedWebbBessel beams have attracted considerable interest because of their unique non-diffractive, self-healing characteristics. Different approaches have been proposed to generate Bessel beams, such as using axicons, diffractive optical elements, composite holograms, or spatial light modulators. named individualsWebbWe demonstrate that nondiffracting beams can be generated with an arbitrary transverse shape. In particular, we show that the azimuthal complex modulation of the angular … namedi high schoolWebbThese nondiffracting X waves can be almost exactly realized over a finite depth of field with finite apertures and by either broadband or bandlimited radiators. With a 25-mm diameter planar radiator, a zeroth-order broadband X wave will have about 2.5-mm lateral and 0.17-mm axial -6-dB beam widths with a -6-dB depth of field of about 171 mm. medway water companyWebbSuch waves constitute an essential generalisation to several kinds of acoustic and optical beams, such as Bessel beams and self-imaging waves. Additionally, rotationally periodic waves also comprise pulsed wave forms that may propagate with a velocity independent of the speed of light (or sound) in the particular medium. medway water boardWebb20 feb. 2024 · 1、本文档共计 5 页,下载后文档不带水印,支持完整阅读内容或进行编辑。 2、当您付费下载文档后,您只拥有了使用权限,并不意味着购买了版权,文档只能用于自身使用,不得用于其他商业用途(如 [转卖]进行直接盈利或[编辑后售卖]进行间接盈利)。 name dillon meaningWebbWe review our recent results applying the stable nonlinear propagation of nondiffracting Bessel beams to femtosecond laser ablation in dielectric materials.
