Abstract
Measurements of the total energy reflected from crystalline and amorphous silicon illuminated by a femtosecond laser pulse are reported, for wavelengths of 0.62 and 0.31 μm. The results are interpreted by use of a highly nonlinear regime of light propagation in the dense plasma of electrons and holes (). Densities higher than are reached. We demonstrate that free-carrier absorption is dominated by collisions.
