| Outline of Final Research Achievements |
It's possible to apply to material synthesis using laser induced shock waves. A laser induced shock wave depends on the intensity of the laser, and to become high, pulse laser is generally used. High pressure is obtained more as a pulse width is short, but most of an ingredient parts which exposed high pressure are lost by laser ablation, and a shock wave inside the material will be decreased as well as an end of a laser irradiation suddenly. In this study, chirp pulse laser, and super-long pulse laser was used to control breakdown of glass, confine a shocked material in glass and quench to recover unstable matter.
