Abstract
An optical tweezers system using laser beams with a Gaussian intensity profile
and doughnut intensity profiles made by hollow core optical fiber and axicon
lenses, respectively, was constructed. The axial trapping efficiencies for the
three intensity profiles were measured and compared with each other. The
particle size dependence of axial trapping efficiencies in the range of the
particle diameter from 1 to 20 μm were analyzed by using the modified
ray optics model [Appl.
Opt. 33, 1735 (1994) [CrossRef] ].
