One and Two Photon Induced Photodegradation of DANS Films

Abstract

Dye doped solids have been investigated for a decade for non-linear optical applications, especially for integrated optics. In some areas, their “single shot” performance has now reached levels which compete with the best ferroelectrics materials and thus encourages their practical usage. However, a key question remains to be answered : how stable is their performance with time when used in given devices and under operational conditions ?
