Rotation of microparticles with Bessel beams generated by diffractive elements

Abstract: We show that imaging a non-diverging Bessel beam by a spherical lens leads to the generation of a diverging Bessel beam. Expressions for the projections of the Umov-Poynting vector for a two-dimensional TE-polarized Bessel beam and a three-dimensional paraxial linearly polarized Bessel beam are derived. A fifth-order Bessel beam is produced using a single optical element-a 16-level phase-only diffractive helical axicon fabricated using electron beam lithography. This beam was successfully used to trap and rota… Show more

“…Numerical simulation of integrals (6) shows that they have the typical maximum at q 1 + q 2 = q 3 , which value coincides approximately with the corresponding value for interaction of beams of zeroth-order [14]. Note that the above relation between transverse wave numbers q 1 + q 2 = q 3 indicates to collinear type of synchronism for plane-wave component of Bessel beams (see also Fig.1).…”

“…Они используются для манипуляции микрочастицами: для одновременного захвата нескольких микрочастиц вдоль оптической оси [19,20], для вращения одной или нескольких частиц вокруг оптической оси [21]. С помощью пучков Бесселя можно захватывать и уско-рять отдельные охлаждённые атомы [22,23].…”

“…This means the Bessel beam should be strongly nonparaxial (θ 0 > 60°) to realize universal pulling. In spite of considerable challenges in generation of such strongly nonparaxial Bessel beams, the hypergeometric laser beam [139] is a promising candidate to possess the required nonparaxiality. On the other hand, the scattered field can be focused in the forward direction by controlling the interaction of the electric and magnetic dipoles.…”
