铝靶对短脉冲强激光反射率的饱和现象

SATURATED PHENOMENA OF THE REFLECTIVITY OF SHORT PULSE HIGH INTENSIVE LASER ON ALUMINUM TARGET

计算了铝靶对Ｓ极化短脉冲强激光的反时率的饱和段，将所得结果和Ｈ．Ｍ．Ｍｉｌｃｈｂｅｒｇ的实验结果进行了对比，二者十分一致。并对此饱和现象作了物理解释，认为是由电子的热运动和相互作用所引起的。

In this paper, the reflectivity of short pulse high intensivelaser on aluminum target at the saturated section is calculated. The theoreticalresults are in accord with the experimental results of H.M. Milchberg et al. The behavior of saturation is considered that due to the thermal motion of the electrons and their mutual actions.
