The Influence of Parameters on Stable Space-time “Pillar” in Optical Tweezer using Counter-propagating Pulsed Laser Beams

摘要

In this article the stable process of the optical tweezer using the pulsed counter-propagating Gaussian beams is investigated using the Langevin equation with optical gradient force. The influence of parameters as the total energy, the beam waist, the radius of particle and the viscosity of fluid on the dimension of the stable space-time “pillar” is simulated and discussed.
