Laser absorption by overdense plasmas in the relativistic regime

J R Davies2009年Plasma Physics and Controlled FusionIF 2.2出版社

Laser absorption is reviewed in the context of fast ignition inertial fusion. This leads us to consider laser absorption by overdense plasmas for values of intensity times wavelength squared (Iλ2) greater than 1010 W (1018 W cm−2 µm2), which corresponds to the onset of relativistic electron motion in the laser fields. A collection of published absorption values obtained in laser–solid experiments and in numerical modelling of laser–plasma interactions is presented.

レーザー吸収は、高速点火慣性核融合の文脈において概説される。これにより、強度と波長の二乗の積(Iλ²)が10¹⁰ W cm⁻² μm²を超える場合の、過密プラズマによるレーザー吸収の考察へと導かれる。これは、相対論的電子運動の開始に対応する。レーザー・固体実験およびレーザー・プラズマ相互作用の数値モデリングにおいて得られた、公表済みの吸収値の集成が提示される。
