Bessel beams: Diffraction in a new light
David McGloin,Kishan Dholakia +1 more
TL;DR: In this article, the theoretical foundation of the Bessel beam is described and various experiments that make use of Bessel beams are discussed: these cover a wide range of fields including non-linear optics, where the intense central core of the bessel beam has attracted interest; short pulse non-diffracting fields; atom optics, and optical manipulation where the reconstruction properties of the beam enable new effects to be observed that cannot be seen with Gaussian beams.
Journal ArticleDOI
Simultaneous micromanipulation in multiple planes using a self-reconstructing light beam
TL;DR: Bessel beams do not diverge and, furthermore, if part of the beam is obstructed or distorted the beam reconstructs itself after a characteristic propagation distance, which may be utilized within optical tweezers to trap particles in multiple, spatially separated sample cells with a single beam.
Journal ArticleDOI
Spin-to-orbital angular momentum conversion in a strongly focused optical beam.
TL;DR: It is demonstrated that optical spin-to-orbital angular momentum conversion can occur in a homogeneous and isotropic medium and that the orbital rotation speeds of trapped particles are altered because of this conversion as predicted by theory.
Journal ArticleDOI
Observation of the transfer of the local angular momentum density of a multiringed light beam to an optically trapped particle.
Veneranda Garcés-Chávez,David McGloin,Miles J. Padgett,W. Dultz,Heidrun Schmitzer,Kishan Dholakia +5 more
TL;DR: The radial dependence of the observations of the spinning and orbital motion of a microscopic particle trapped within a multiringed light beam is found to be in close agreement with the accepted theory.
Journal ArticleDOI
Interfering Bessel beams for optical micromanipulation.
TL;DR: The self-healing properties of interfering Bessel beams allow the simultaneous manipulation and rotation of particles in spatially separated sample cells in optical tweezers and rotators.
