摘要
对聚焦激光光束焦深的不同定义作了比较分析，并对基模高斯光束的光强分布作了数值计算，作出了等光强分布曲线。同时对高阶模情况也作了一定分析。对不同情况下激光光束焦深的合理选用进行了讨论。
Different definitions about focal depth of Gaussian Beam are compared and analyzed. A graph of equivalent optical intensity curves formed by numerical calculating is obtained. And how to select suitable focal depth value is discussed.
