We show the effect of a 10-megahertz acoustic radiation perpendicular to the focused laser beam with the power of 5mW. We calculated the theoretical trajectory of a particle in the presence of optical and acoustic forces. By applying the acoustic radiation, the particle wiggles in the optical trap. Increasing the acoustic force causes the particle to escape from the optical trap and localization in a pressure nodal plane.
