  1. In this paper , the parameters of an elliptic Gaussian beam passed through a double concave cylindrical lens are derived , by using the theory of Gaussian beam propagation and the ABCD Law . And the way to improve the effect of line-focus is pointed out .

    利用高斯光束的传播理论和ABCD定律,导出了椭圆高斯光束经一双凹柱透镜变换后的光束参量公式,指出了提高线聚焦效果的途径。
