【Abstract】 We analyze the effect on the optical radiation pressure for corpuscules by laser microbeam.On the basis of constructing laser microbeam system we manipulate hollow dielectric spheres in suspension with optical trap,it validates the kinetic performance of the laser trap.The optical trap can manipulate,deflect,and rotate corpuscules.It can seize a few corpuscules at the same time.We study the kinetic performance of the laser trap exerted on dielectric spheres from theory and experimentation.更多还原
