| Research Abstract |
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.
