摘要：
The scattering characteristics of a Gaussian laser beam and plane beam through spherical particle were studied. The incident field and scattering field of the Gaussian beam are expressed in spherical harmonic function, it's expansion coefficient expression is given. Using of Matlab programming calculation, we simulate the spherical particle scattering intensity for two light beams, The results of the simulation are discussed, and the comparative analysis to plane wave scattering law were made. Results show that the scattering intensity distribution of Gaussian beam is different from the plane wave scattering law,. But under the condition of big waist radius, the scattering laws have a lot in common with the plane wave.
