Repetitive Pulse Detonation by Laser Ablation Induced Liquid Jet

本研究是对前人关于明显降低透明材料界面激光烧蚀阈值影响的研究的延伸。这种效果与激光方向有关。对于透明流体组合，发现激光烧蚀后是高速液体射流，由于射流尖端的雾化速度非常快，射流慢化速度非常快。结果表明，这一现象与影响、能量和光束轮廓有关。根据含能液体材料的特性，得到了特征化的雾化过程。

Present study is an extension of our previous study concerning appreciable reduction of laser ablation threshold fluence of transparent material interface. This effect is laser direction dependent. For transparent fluid combinations, it is found that laser ablation is followed by high-speed liquid jet with very fast slow down due to very fast atomization at the jet tip. It is shown that this phenomenon depend on fluence, energy, and beam profile. We obtained characteristic atomization process depending on energetic liquid material properties.
