5. 短パルス紫外レーザー照射による気体・液体中での衝撃波の発生と応用

Research Project

Research Category	Grant-in-Aid for Scientific Research on Priority Areas
Research Institution	University of Fukui
Principal Investigator	香川喜一郎福井大学, 教育学部, 助教授
Project Period (FY)	1992Completed
Keywords	衝撃波 / レーザープラズマ / 衝撃波ブラズマ / レーザー発光分光分析 / 水中衝撃波
Research Abstract	炭酸ガスレーザーはパルス幅が比較的広しために、衝撃波プラズマの初期過程を見ることはできなかった。今回エキシマーレーザーを用いることでこれが可能となった。レーザー照射後200nsで発光の矢端は立上りを見せ始め、400nsで明らかに衝撃波が生じていることが観測された。この先端は時間と共に移動し、先端の位 ...

7. 減圧下での短パルスレ-ザ-照射による衝撃波プラズマの研究

Research Project

Research Category	Grant-in-Aid for Scientific Research on Priority Areas
Research Institution	University of Fukui
Principal Investigator	香川喜一郎福井大学, 教育学部, 助教授
