Motivated by the recent optical trapping experiments using ultra-short pulsed lasers [Opt.Express 18,7554 (2010); Appl.Opt.48,G33 (2009)],in this paper we have re-investigated the trapping effects of the pulsed radiation force (PRF),which is induced by a pulsed Gaussian beam acting on a Rayleigh dielectric sphere.Based on our previous model [Opt.Express 15,10615 (2007)],we have considered the effects arisen from both the transverse and axial PRFs,which lead to the different behaviors of both velocities and displacements of a Rayleigh particle within a pulse duration.
