Time-Resolved Pulse Propagation in Glass in Single-Shot

Abstract

We report time-resolved pulse self-steepening and temporal splitting in flint glass (SF11) in single-shot using broadband frequency-domain streak camera (B-FDSC). The broadband ($60$ nm) probe beam generated through a compact coverslip array provides $\sim 40$ fs temporal resolution. The experimental results support the theoretical model of pulse self-steepening and indicate that multiphoton ionization (MPI) initiates the pulse splitting process in glass. We perform a three-dimensional simulation to verify the experimental results.
