Laser Trapping Particles in a Focused Gaussian Beam

Yang Xiaoli;Wang Junbo;FengZhichao(Inst.of Applied Physics,UEST of China Chengdu 610054)  
Using the complex-source-point spherical wave theory,this peper derives the formulas for the radiation pressure of a focused gaussian beam exerted on a particle.The numerical results of the radiation pressure and their physical interpretations are presented.A sphere located in a strongly focused laser beam is pressured not only in beam axis direction,but also in transverse direction when the sphere in the beam goes away from the beam axis.The experiment on stable optical levitation of transparent spheres in air first in China is completed It is believe that the technique will be widely used in biological technology,materials science,and aerosol.
