Outline of Final Research Achievements

The purpose of this study is to generate dissociation reaction by obtaining high pressure state of carbon dioxide by laser induced shock wave and to observe the product in the recovery process. In order to obtain this compressed state, since the compression time is an important parameter in addition to the pressure value itself, we developed a laser compression system with a pulse width of sub nano seconds. We will also prepare experimental systems using backup materials and plan to collect and analyze carbon dioxide.
