摘要
为了直观再现腔镜倾斜对光束分布的影响,用FoxLi数值迭代法及图像重构法,绘得方形镜虚共焦腔在不同倾角下近场及远场光强的三维分布图,并对倾斜后光束特点进行了讨论。结果表明,腔镜倾斜使光束近场分布变差,致使远场光束发生畸变,质量下降。
To display the effect of mirror misalignment on beam d istributions more intuitively,Fox-Li iterative diffraction calculation method w as used to solve the Fresnel integral equation and three-dimension figures of e ffected beam were presented.The results indicate the beam in both near and far f ield will be aberrated and simultaneously the beam quality will be deteriorated when misalignment appears.
