Abstract

We present an advanced experimental dual-beam set-up for optical manipulation of airborne particles in air. This system employs an adaptive optical element to control properties of counter-propagating beams overlapping in a sample chamber. Furthermore, it 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 demonstrated variety of applications of this system ranging from liquid droplet fusion, multiple beams manipulation and precise airborne particle delivery via optical conveyor belt.
