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。
It is found that the emission of airgel planar targets is obviously different from that of ordinary planar targets, mainly through the research on X-ray and harmonic emission of laser plasma produced by plane targets of aerogels. Airgel targets emit thin X-ray light, prone to the second harmonic sub-peak structure, which is due to the low density of the airgel target itself easily excited by ion acoustic decay instability caused.
