摘要: 平板宽波导CO2激光器波导内光场分布满足亥姆霍兹方程。在给定条件下,对光场分布方程进行求解,获得了极化模 EHnmx和EHnmy 的表达式。通过计算机计算,得出了在3×8 mm2波导放电区中所存在的EH1.16极化模归一化理论分布曲线,其曲线与实验观测结果符合得很好。

Abstract: The optical field distribution in wide planar-waveguide CO2 gas laser satisfies Helmholtz equation.Under certain given conditions,expressions of the polarized modes EHnmx and EHnmy are obtained by solving optical field distribution equation.The present computation gives a normalized theoretical distribution curve of EH1.16 polarized mode existed in 3×18mm2 waveguide discharge area.The curve is consistent with the experimental results.

Key words: wide planar-waveguide CO2gas laser, polarized mode, normalized distribution curve
