Optical beam engineering for nanoscale structuring of transparent materials

This Beam engineering solutions are provided to enhance the light-matter interaction processes for extreme scale material structuring applications. We present experimental results demonstrating the potential use of spatially shaped laser pulses (Bessel pulses in particular) for high aspect ratio material structuring applications. We also provide simulation results on nonlinear beam propagation in glass, which show that in addition to the spatial shaping, temporal shaping of a laser pulse can significantly increase the effectiveness of the light-matter interaction processes.
