Abstract

We report on the refractive index grating formation by filamentary propagation of femtosecond pulses in fused silica. The relevant exposure and work cycles are considered both experimentally and through numerical study, involving a model of light filaments supported by conical wave, capable to capture permanent glass refraction index changes.
