Mechanical effects of optical vortices
N. R. Heckenberg, M. E. J. Friese, T. A. Nieminen +1
We concentrate on the forces and torques exerted on transparent and absorbing particles trapped in laser beams containing optical vortices. We review previous theoretical and exper…
Optical trapping of absorbing particles
H. Rubinsztein-Dunlop, T. A. Nieminen, M. E. J. Friese +1
Radiation pressure forces in a focussed laser beam can be used to trap microscopic absorbing particles against a substrate. Calculations based on momentum transfer considerations s…
Optical torque controlled by elliptical polarization
M. E. J. Friese, T. A. Nieminen, N. R. Heckenberg +1
We show theoretically and demonstrate experimentally that highly absorbing particles can be trapped and manipulated in a single highly focused Gaussian beam. Our studies of the eff…
Optical alignment and spinning of laser-trapped microscopic particles
M. E. J. Friese, T. A. Nieminen, N. R. Heckenberg +1
Light-induced rotation of absorbing microscopic particles by transfer of angular momentum from light to the material raises the possibility of optically driven micromachines. The p…
