Recent work on laser produced plasmas is presented focusing on the theoretical studies of four topics which have been carried out at the Institute of Laser Engineering (ILE), Osaka University, after a brief explanation of the six physics issues to be studied for plasma physics related to the laser fusion. The importance of integrated code development is emphasized and it is shown that the growth of the Rayleigh-Taylor instability at the ablation front is reduced partly due to non-local electron transport. Non-uniformity of implosion dynamics is studied by comparing a two-dimensional simulation with a spectroscopic post-processing package. It is concluded that all the available experimental data are consistently explained. The fast-ignition with ultra-high power laser is studied. The ignition criteria are clarified with a two-dimensional burning wave simulation. The possibility to study astrophysics by designing model experiments with intense lasers is introduced. The computational design of models of the ejecta-ring collision of SN1987A is shown by comparing with the event in the space.

レーザー生成プラズマに関する最近の研究を、大阪大学レーザー工学研究所(ILE)において実施された4つのテーマの理論的研究に焦点を当てて紹介する。まず、レーザー核融合に関連するプラズマ物理において検討すべき6つの物理的課題を簡潔に説明した後、統合コード開発の重要性を強調し、非局所電子輸送によってアブレーション前面におけるレイリー・テイラー不安定性の成長が部分的に抑制されることを示す。次に、分光パッケージを組み込んだ2次元シミュレーションと実験を比較することにより、爆縮ダイナミクスの非一様性を検討する。その結果、利用可能な実験データはすべて統一的に説明できることが結論づけられる。さらに、超高強度レーザーを用いた高速点火の研究について、2次元燃焼波シミュレーションにより点火条件を明らかにする。最後に、強力レーザーを用いたモデル実験による天体物理学の研究可能性を紹介し、SN1987Aの噴出物と環状星雲の衝突に関するモデルの計算機設計を、実際の宇宙での現象と比較して示す。
