Abstract :
In this paper, we report on the self-fabrication of sub-micrometer-sized void array in fused silica using Ti:sapphire femtosecond lasers. We have investigated the effect of the focusing condition on the shape of the fabricated void. It is found that the shape of the voids was varied with the depth of a focusing point from the sample surface, because the self-focusing process has a significant effect on the generation of the voids
