摘要
利用快速汉克尔变换算法研究了高功率激光在自由空间传输过程中形成低频调制的规律 ,给出了衍射调制深度与光束宽度及传输距离等参数之间的变化关系。对选择传输参数提供了参考依据。
The fast Hankel transformation algorithm is used to study the diffractive modulation property of laser beam propagation in high power laser facility.It is shown that the fill factor or intensity modulation contrast of modulation ring due to the diffraction is related to the Fresnel number of laser system.
