Abstract

In the framework of the consistent microscopic theory, universal analytic expressions describing absorption of laser pulses of an arbitrary duration in an optically dense medium have been derived, and their limiting cases have been considered. For the Gaussian and Lorentzian spectral profiles, simple expressions have been obtained for the absorption coefficient as a function of dimensionless parameters (optical thickness of the medium, the pulse duration and carrier frequency). Based on the performed calculations, the effect of the optical thickness of the medium on the dependences of the absorption coefficient on the pulse parameters has been revealed.

超短激光脉冲在光密集介质中的吸收
在一致微观理论的框架下,导出了描述光密集介质中任意持续时间激光脉冲吸收的通用解析表达式,并考虑了它们的极限情况。对于高斯谱和洛伦兹谱,我们得到了吸收系数随无量纲参数(介质的光学厚度、脉冲持续时间和载频)的函数的简单表达式。通过计算,揭示了介质的光学厚度对吸收系数随脉冲参数的依赖关系的影响。
