| 摘 要： | 以强激光应用在化学工程中所遇到的物理问题为背景，研究介质的热透镜效应、吸收强弱、吸收饱和程度以及介质的流动等因素对激光传播的影响。根据一组简化模型，提出了描述光场行为的方程组，给出了不同情况下介质的温度分布情况、光线在介质中的变化行为以及激光光强的分布化情况。所得结果，对光化学工程设计有一定的参考价值。

| Abstract: | The medium effects of thermal lens, linear absorption coefficients, absorption saturation, and flow directions on high laser propagation have been studied with the background of laser applications in photochemical engineering. A set of equations based on a simple model is proposed to discribe the light field. The temperature distributions,light behaviors, and changes of laser intensity distribution in the absorption medium are obtained for different cases. |

| Keywords: | intense laser absorption saturation non-linear dispersion propagation. |
