摘　　要：采用二阶矩的方法,以Laguerre-Gauss光束为例,将三维光场展开成二阶矩参数矩阵,通过对该矩阵的分析表明通过对光束二阶矩参数矩阵中的扭转参量〈xθy〉和〈yθx〉的计算,能够得出激光束的轨道角动量的性质.并介绍了暗中空激光束轨道角动量传递给微粒所引起的微粒光致旋转效应,分析了激光束轨道角动量所引起的光致旋转机理.The character of the hollow laser beam second moment method. The Laguerre and its orbital angular momentum are analyzed by using the - Gauss beam is taken to be an example for the analysis. The optical rotation caused by the orbital angular momentum transferring form laser beam to particle was elaborated. So was the principle of the optical rotation.
