Abstract
We report on the investigation of crossed-Bessel-beam and hybrid Bessel-Gauss configurations for optical trapping of microscopic particles. The non-diffractive nature of the Bessel beam removes the need for high-NA optics. Crossed beam configurations allow creating trapping volumes with small aspect ratio, in comparison to single-beam Bessel traps that create wave-guide like structures. We present numerical simulations of said geometries and present experimental data of in-situ Bessel beam forces on polystyrene beads as precursor to the realization of a random access Bessel trap.
