激光聚变的理论和实验研究是一项综合性的应用研究.为了弄清激光靶耦合的物理规律,作各种分解研究是很有必要的.在激光间接驱动内爆研究中,要求激光以某一角度进入黑洞靶中与靶相互作用.作为一个分解问题,本文在几何光路近似和一维密度分布的假定下对钕玻璃激光与金(Au)平面靶耦合的吸收作了自洽这这的数值计算,通过结果分析给出了激光吸收效率随激光入射角、强度和波长的变化规律,同时还给出激光吸收区电子温度、X射线转换效率随激光入射角的变化规律.模型计算值与国内外已发表的理论和实验结果作了比较,其定性趋势和定量结果都不同程度地符合.
Laser fusion theory and experimental study is a comprehensive application of research.In order to understand the physical laws of laser target coupling, for various decomposition studies is necessary.In the laser indirect impulse implosion study, the laser required to a Angle into the black hole target.As a decomposition problem, this article makes self-consistent absorption of neodymium glass laser and gold (Au) plane target coupling under the assumption of geometric optical path approximation and one-dimensional density distribution The results show that the laser absorption efficiency changes with the incident angle, intensity and wavelength of the laser, and the law of the electron temperature and the X-ray conversion efficiency with the laser incident angle are also given. The calculated values of the model At home and abroad have published theoretical and experimental results were compared, the qualitative trends and quantitative results are to varying degrees in line.
