【Abstract】 We discuss and analyze the magnitude of the force generated by light rays and the optical trapping principle of highly focused laser beam. The experimental results of laser manipulating biological particles by He-Ne and Ar + laser with different modes will be presented in this paper, which is very useful for understanding the kinetic performance of the laser tweezers and its applications.更多还原
