强激光与气凝胶靶相互作用的二次谐波与X射线发射的实验研究
Second Harmonic and X ray Emission from Aerogel Targets Irradiated with Intense Laser Pulses
摘要
主要通过对气凝胶多孔材料平面靶产生的激光等离子体Ｘ射线和谐波发射的研究,发现气凝胶平面靶的光谱发射与普通平面靶明显不同。气凝胶靶发射的Ｘ射线光厚较薄,容易产生二次谐波的次峰结构,这是由于气凝胶靶本身的低密度特性容易激发离子声衰变不稳定性而引起的。
Abstract
The interaction between intense laser pulses and aerogel targets was studied. The X ray emission and second harmonic generation are different from those of the plane targets. Different plasma status relative to these special targets was studied.
