Abstract :
This study demonstrates self-assembling of a sub-micrometer-sized void array in fused silica using an amplified 1-kpps Ti:sapphire femtosecond laser. The effect of the focusing conditions of numerical aperture, laser energy, and pulse number on the shape of the fabricated void is also investigated
