粒子在单束激光势阱中的束缚力
The forces exerted by a single laser trapping on particles
摘要
本文在几何光学近似下,考虑到强聚焦高斯光束的结构,导出了TEM00高斯光束对透明球状粒子作用力的计算公式,数值计算给出了单束激光阱存在的条件,并讨论了光吸收的影响。
Abstract
The formulas of the forces applied by a TEM00 Gaussian laser beam on the transparent spheres are derived under the apporximation of geometric optics with regard for the contraction of a strongly focussed Gaussian optical beam. The numerical results show the condition of the laser trapping of a single lassr beam. The effects of the absorption of light on the trapping are also discussed.
