Abstract

Both the "after-pulse effect" and the dynamic characteristics of photostructural transformations induced in glassy As_0.5Se_0.5 films by pulsed 532 nm excitation have been studied. The after-pulse effect investigation demonstrated more than a 10³ times increase of the photosensitivity in case of pulsed excitation. Dynamic characteristics showed a dual time scale behavior and different intensity dependence of transient and long time scale signals. The obtained data indicate that the strong increase of photosensitivity following short intense pulsed light excitation is due to a two-photon effect that aids the process of structural rearrangement.
