III. 激光与大尺度等离子体的相互作用
在激光聚变实验研究中，激光与大尺度等离子体相互作用会产生各种参量不稳定性。一般来说，这些参量不稳定性对激光聚变是有害的，被认为是导致激光聚变点火失败的关键因素。掌握激光与大尺度相互作用的规律对激光聚变极为重要，本人从博士研究生阶段开始长期从事这个方面的研究。

IV. 激光驱动的X射线源及其诊断技术
高功率激光脉冲与物质相互作用时，可以产生高亮度的X射线。这些X射线不仅可用于惯性约束 聚变间接驱动，而且可以作为诊断诸多高能量密度物理过程的探针，因而发展激光驱动的X射线源极为重要。工作以后，本人通过课题组的研究生以及青年教师介入这个研究方向。

V. 等离子体物理基本过程及Fokker-Palnck模拟
激光等离子体密度高，带电粒子之间的库伦散射对等离子体中的波动和能量输运有重要影响。在等离子体物理中，库伦散射的影响通常采用Fokker-Planck碰撞项刻画，但Fokker-Planck碰撞项通常难以解析处理，一般需要借助数值模拟工作以后，本人对此方面的研究保持了长久的兴趣。
