通过定义一个新的广义曲率半径，即1qNL=1R−jσπW2λ，其中（σ − 1）是光束功率与自聚焦临界功率的比值，可以在近轴光学系统中考虑自聚焦效应。
It is shown that self-focusing can be taken into account in an optical paraxial system by simply defining a new generalized radius of curvature, namely, 1qNL=1R−jσπW2λ,where (σ − 1) is the ratio of the power of the beam to the critical power for self-focusing.
