圆形球面虚共焦非稳腔的三维数值研究
-
摘要: 通过对1/2共焦腔和稳定腔的计算,考查了同三维菲涅耳积分方程相应的C8程序的可靠性。对激光在三维圆形球面虚共焦非稳腔中的传输作了计算和分析。取相同的远场传输距离且放大率由大变小时，强度分布由近场的投影分布逐渐趋于远场的高斯、超高斯分布。

Abstract: We examined carefully the reliability of C8 code according to 3D Fresnel integral equations． The transmission behavior of the short wavelength laser in virtual confocal cavity with circular mirrors of spherical surfaces were computed and analyzed. Under condition of the same transmission distance, the distribution of farfield intensity changes from the projection of nearfield intensity distribution to the distribution of superGaussian when magnification on m changes from 10 to 1.42． -
