| Outline of Final Research Achievements |
A system tpr transport the nano or fine particles by using an underwater shock waves generated by irradiating a thin film of metal with laser irradiation has been investigated experimentally. In this study, we investigated the generation of high frequency underwater shock waves and the momentum transport of the resulting fluid using highly repetitive laser and fiber, and the experiment of shock wave interference also conducted to realize multiple shock waves interaction by fiber, The cross shock waves generated as a result of interference were measured and the propagation characteristics of the shock waves were observed. It was confirmed that occurrence of high frequency shock wave can occur at about several 10 Hz, but it was confirmed that it was hard to generate it at higher frequency. Whereas, the propagation of effectiveness to generated the shock waves with a fiber has been confirmed.
