二氧化硅气凝胶是非常适合于高功率非线性光学应用的材料。在这种情况下，非平凡的热性质可能会引起光学激波的产生，而光学激波的产生也会受到多孔凝胶的结构无序的影响。在这里，我们报道了一项关于束腰和输入功率的实验研究，并确定了在二氧化硅气凝胶中产生波破碎现象的不同区域。(C)2014年美国光学学会
Silica aerogels are materials well suited for high power nonlinear optical applications. In such regime, the non-trivial thermal properties may give rise to the generation of optical shock waves, which are also affected by the structural disorder due to the porous solid-state gel. Here we report on an experimental investigation in terms of beam waist and input power, and identify various regimes of the generation of wave-breaking phenomena in silica aerogels.
