tailieunhanh - An optical tweezers using Hollow-Gaussian for both low-and high-index particles

An optical system to transform the laser Gaussian beam into the Hollow-Gaussian one is proposed and designed. Based on the principles of ray optics, the expressions describing the laser intensity distribution behind optical system and optical transverse gradient force acting on the both low- (refractive index ratio, m | An optical tweezers using Hollow-Gaussian for both low-and high-index particles
