摘要
本文试从角分布概念来描述光束在自由空间的传播情况,通过试验数据来验证概念的实际意义,并提出激光发散角是由光束的几何张角和角分布二部分来定义的。
The article seeks to describe from the concept of angular distribution the beam propagation in free space in such a way as to prove the actual validity of this concept through the test data acquired, and thus put forward the definition that beam divergence is depend on the geometrical subtended angle of the beam and the angular distribution.
