Abstract
Existing theory for stationary laser pulse propagation in absorbing media for times greater than the acoustic transit time is compared with experiments. Collimated and focused Gaussian beams as well as unstable resonator type beams are investigated. Good agreement is reached for all experimental conditions for collimated beams, and at higher energy deposition significant deviations are observed for focused beams.
摘要
将现有的关于吸收介质中稳态激光脉冲传播时间大于声传播时间的理论与实验进行了比较。研究了准直高斯光束、聚焦高斯光束以及非稳腔型光束。对于准直光束的所有实验条件都达成了良好的一致性，而对于聚焦光束，在较高能量沉积时观察到了显著偏差。
