Optical trapping and manipulation of light-absorbing particles by means of a Hermite–Gaussian laser beam

A. P. Porfirev and R. V. Skidanov

This paper describes simultaneous optical trapping and displacement of several nonspherical light-absorbing microparticles in air by means of a focused Hermite–Gaussian laser beam (laser mode TEM10, radiation wavelength 457 nm). Agglomerations of carbon nanoparticles are displaced in three dimensions by distances of the order of a millimeter. The structure of the Hermite–Gaussian beam used here made it possible to displace microparticles simultaneously along two parallel trajectories in space.
