Abstract:

{We used a new broadband spectroscopic technique to measure the dielectric function of GaAs over the spectral range of 1.5 - 3.5 eV following intense 70-fs laser excitation. The results provide the most detailed information thus far on the electron and lattice dynamics both above and below the fluence threshold for permanent damage
