Experimental optical trapping of micro-particles with Frozen Waves

Abstract

This work presents the first optical trapping experimental demonstration of micro-particles with Frozen Waves. Frozen Waves are an efficient method to model longitudinally the intensity of non-diffracting beams obtained by superposing co-propagating Bessel beams with the same frequency and order. The experimental setup of a holographic optical tweezers using spatial light modulators has been assembled and optimized. We investigate the optical force distribution acting on micro-particles of two types of Frozen Waves.The results show that it is possible to obtain greater stability for optical trapping using Frozen Waves. The significant enhancement in trapping geometry from this approach shows promising applications for optical tweezers, micro-manipulations over a broad range.
