Thermal blooming of a pulsed, focused Gaussian laser beam in a gas is studied for a specific model of gaseous heating. Analytic results in the limit of times both long and short compared with the sound transit time across any part of the beam are presented as irradiance profiles at any range as a function of time. Experiments that can be done with present laser technology to test the theoretical predictions are suggested.
针对一种特定的气体加热模型,研究了脉冲聚焦高斯激光束在气体中的热晕效应。给出了在与光束任何部分的声传播时间相比时长和短两种极限情况下的解析结果,即作为时间函数的任意距离处的辐照度分布。还提出了利用现有激光技术可进行的用以检验理论预测的实验。
