Propagation of ultrafast pulses in transparent media — Hatem Dachraoui, •Christian Oberer, Martin Michelswirth, and Ulrich Heinzmann — Molecular and Surface Physics, Faculty of Physics, Bielefeld University
Time- and space-resolved optical transmittance has been used to study the propagation of a femtosecond laser pulse in transparent media (fused silica, LiF) at various input laser energies (5 - 50 TW/cm2). The results identify different regimes of propagation, revealing the interplay between self-focusing, multiphoton absorption, and plasma defocussing.
