✦ Synopsis
Non-photochemical hole-burning is a reliable technique for the study of optical dephasing in organic glasses. This is proved by an analysis of the holewidth dependence on sample preparation, optical density, temperature, burning time and laser power. Holes were detected simultaneously by fluorescence excitation and transmission, and conditions for the occurrence of slow relaxation processes in the glass were found.
