研究了高功率激光系统光束传输的基本算法并编制了相应的程序编码 .结果表明 ,光束传输过程中形成的衍射调制环数与系统中空间滤波器小孔光阑的大小(以衍射极限倍数度量 )以及传输系统的Fresnel数的综合影响有关 ;对于包含多级空间滤波器和自由空间的复杂光学系统 ,可以采用算子互换性将复杂系统等效为适当选取参数的单元元件进行计算和设计 .
The basic algorithm of beam transmission in high power laser system is studied and the corresponding program codes are compiled.The results show that the number of diffraction modulation rings formed in the beam transmission and the size of the aperture aperture of the spatial filter in the system (measured by diffraction limit multiples ) And the Fresnel number of the transmission system. For complex optics systems with multistage spatial filters and free space, operator-interchangeability can be used to compute and design complex systems as elements of the appropriate parameter selection .
