Paper Abstract

We present an advanced configuration for optical manipulation of micro- and nano-objects employing adaptive optical element to control properties of more counter-propagating beams overlapping in a sample chamber. This system can eliminate optical aberrations in both pathways, online re-align the system remotely from a computer interface, arbitrarily switch in real time between various beams types (vortex, Gauss, Bessel etc.) and their spatial intensity distributions (beam width, vorticity etc.). We demonstrate variety of applications of this set-up ranging from formation of spatial solitons, longitudinal optically bound 1D, 2D, and 3D colloidal structures, precise particle delivery via optical conveyor belt, stable confinement of low-index particles or nanoparticles, controlled rotation or swing of heterogeneous living microorganisms.
