激光黑腔靶等离子体相互作用研究现状和发展趋势

Present Status and Development Trends in Interaction Studyon Laser HohlraumTarget and Plasmas

综述近年来围绕美国的“国家点火装置”(NIF)所开展的大尺度激光腔靶等离子体相互作用研究 ,结合国内的研究 ,对抑制受激布里渊散射 (SBS)减少散射光、抑制受激拉曼散射 (SRS)减少超热电子、成丝 (FI)以及激光均匀辐照方法进行了深入的分析和综述。评述了研究现状和取得的成果 ,还分析了该领域的发展趋势 ,提出了我国惯性约束聚变 (ICF)等离子体研究应该注意的一些问题和建议。

Study on interaction of large size laser hohlraum target and plasmas performed around NIF is reviewed, and analyses in depth and comprehensive description were made on the suppression of stimulated Brillouin scattering (SBS) to reduce the scattering light,suppression of stimulated Raman scattering (SRS) to reduce the super thermal electrons,filamentation and the methods to get uniform laser irradiation incorporating with our own research results.The research status and the results achieved were reviewed,the development trend in this field was analyzed,and some problems and suggestions to which attention should be paid in the ICF plasma research in our country were put forward.
