Trapping Rayleigh particles using highly focused higher-order radially polarized beams

► The axial trap distance is increased by high-order radially polarized beams. ► Three-dimensional trap for a particle is related with the order of the beam. ► The trap stability and trap stiffness is also dependent of the order. ► The radially polarized beam of p = 1 order is very valid to trap Rayleigh particles.
