Studies on the properties of warm dense matter based on quantum-statistical theories

用量子统计理论分析了激光产生的热致密物质的电子结构、光吸收系数和碰撞弛豫速率。本文研究了强度大于10 ~（13）W/cm ~ 2的真空紫外激光脉冲在固体锂中的吸收饱和和非线性传输。我们还开发了一种基于能带计算的方法来评估简单金属的光吸收系数的光子能量从紫外线到X射线区域。

Electronic structures, photoabsorption coefficients and collisional relaxation rates in laser-produced warm dense matter have been analyzed with quantum-statistical theories. Absorption saturation and nonlinear transmission of a vacuum ultra-violet laser pulse through solid lithium have been demonstrated for an intensity greater than 1013W/cm2. We have also developed a method based on energy-band calculations to evaluate photoabsorption coefficients of simple metals for photon energies from ultra-violet to x-ray regions.
