Theory of optical trapping by an optical vortex beam

J Ng, Z Lin, CT Chan - Physical review letters, 2010 - APS
We propose a theory to explain optical trapping by optical vortices (OVs), which are
emerging as important tools to trap mesoscopic particles. The common perception is that the …

MJ Lang, SM Block - American journal of physics, 2003 - ncbi.nlm.nih.gov
Abstract This Resource Letter provides a guide to the literature on optical tweezers, also
known as laser-based, gradient-force optical traps. Journal articles and books are cited for …

Trapping forces, force constants, and potential depths for dielectric spheres in the presence of spherical aberrations

A Rohrbach, EHK Stelzer - Applied optics, 2002 - opg.optica.org
We present and verify a theoretical model that predicts trapping forces (escape forces), force
constants (trap stiffnesses), and trapping potential depths for dielectric spheres with …

Measurements of trapping efficiency and stiffness in optical tweezers

N Malagnino, G Pesce, A Sasso, E Arimondo - Optics Communications, 2002 - Elsevier
We report an experimental study concerning the radial forces of an optical tweezers acting
on spherical polystyrene particles diluted in water solution. The radius of the trapped beads …

Three-dimensional position detection of optically trapped dielectric particles

A Rohrbach, EHK Stelzer - Journal of Applied Physics, 2002 - pubs.aip.org
A theory is presented together with simulation results that describe three-dimensional
position detection of a sphere located in a highly focused beam by back-focal plane …

Theory of optical tweezers

PAM Neto, HM Nussenzveig - Europhysics Letters, 2000 - iopscience.iop.org
We derive an exact partial-wave (Mie) expansion of the axial force exerted on a transparent
sphere by a laser beam focused through a high numerical aperture objective. The results …

Stabilization of an optical microscope to 0.1 nm in three dimensions

AR Carter, GM King, TA Ulrich, W Halsey… - Applied Optics, 2007 - opg.optica.org
Mechanical drift is a long-standing problem in optical microscopy that occurs in all three
dimensions. This drift increasingly limits the resolution of advanced surface-coupled, single …
