摘要

Abstract: There are many reports about the study for highly focused laser-beam gradient forces exerted on dielectric microspheres to date. But the force values calculated theoretically are commonly larger than the actual and effective forces measured in experiment, which indicates that there is a sort of system errors between theory and experiment. In this paper a focusing characteristic study of laser beam affected by the astigmation of slide glass is presented using geometrical-optics method. And it is pointed out that the affection is one of the main factors causing system error mentioned above. !8
