3D Nano-Fabrication Using Controlled Bessel-Glass Interaction in Ultra-fast Modes
Abstract : With a quest to develop rapid and reliable three-dimensional nanofabrication techniques for photonic
and fluidic applications, we exploited the potential of zero-order Bessel beams for fabricating
high aspect ratio nano-structures in fused silica glass. In particular, the energetic conditions towards
stable and uniform nanovoid fabrication were explored, correlating the laser pulse energy and temporal
duration. The underlying carrier and structural dynamics revealed through multiscale timeresolved
microscopy techniques in the case of Bessel pulse excitation of silica glass were also studied.
We discovered different material relaxation pathways corresponding to material modifications
of different morphologies such as increased and decreased refractive index structures.
