The axial optical force exerted on the Mie microsphere particles is calculated quantitatively based on the theory of geometrical optics. According to the calculation results,the relationship between the axial force and some parameters,including laser wave-length,beam waist,laser power,radius of the particle,refractive index and so on,are discussed.
