摘要: 使用级数修正公式研究了非傍轴厄米高斯光束的传输。用数值计算例子说明了修正公式的适用范围。结果表明,在束宽可与波长相比时,修正公式是发散的,并分析了发散的原因。

Abstract: The propagation of Hermite Gaussian beams beyond the paraxial approximation is studied through the series expansion. The validity of the expansion formula is illustrated with numerical examples. It is shown that the formula becomes divergent,if the beam width is comparable with the wavelength. The corresponding physical analysis is also made.
