Paper Abstract

The dynamics of aerosol droplets in a quadruple Bessel beam (QBB) trap and a counter-propagating Bessel beam (CPBB) trap are compared by combining experimental results with simulations of the three-dimensional droplet dynamics. The major focus is on the influence of additional constant and pulsed external forces on the droplet stability and confinement in the two different types of traps. The constant force corresponds to a constant gas flow around the trapped droplet. The pulsed external force is provided by a nanosecond laser. Two types of droplets are studied: Aqueous NaCl droplets which do not absorb at the wavelength of the nanosecond laser and DOP particles which strongly absorb at the wavelength of the nanosecond laser.
