Abstract
Abstract
Two realisations of the pump-probe method have been used to study the time-resolved non-linear optical response of glassy chalcogenides at frequencies near their single-photon and two-photon bandgaps. Photo-excitation of gap states has been revealed as a determining effect for structural, electronic, thermal and optical changes in a glass sample.
