Non-linear reflexion of laser radiation by a plasma layer in a coherent wave description

D. Andersson, H. Wilhelmsson1974年被引用 16Nuclear FusionIF 3出版社

The paper presents a theoretical analysis of the problem of anomalous reflexion of laser radiation by a plasma due to stimulated scattering by ion-acoustic or electron plasma waves (stimulated Brillouin or Raman scattering). A coherent wave (or well-defined phase) description is used to investigate the case of perpendicular incidence on a plasma layer. The reflexion coefficient as found from the analysis is studied as a function of the power of the laser radiation and of the plasma parameters. The results are compared with those obtained from other investigations. Finally, numerical estimates are given for situations of interest for laser fusion.

本論文は、イオン音波または電子プラズマ波による誘導散乱(誘導ブリルアン散乱または誘導ラマン散乱)に起因する、プラズマによるレーザー放射の異常反射の問題の理論的解析を提示する。コヒーレント波(または明確に定義された位相)記述を用いて、プラズマ層への垂直入射の場合を調べる。解析から得られる反射係数は、レーザー放射のパワーおよびプラズマパラメータの関数として研究される。結果は他の研究から得られたものと比較される。最後に、レーザー核融合にとって重要な状況に対する数値的評価が与えられる。
