Abstract

Optical dephasing studies of organic glasses and polymers provide the valuable information about an amorphous system’s dynamics. In the recent years hole-burning and two-pulse picosecond photon-echo were widely used for these purposes. These methods have different characteristic times: minutes and more - for hole-burning, picoseconds - for two-pulse picosecond photon-echo. As a result, in the case of amorphous systems, data obtained by using of these methods correspond to different time scales and are not equivalent [1]. The comparison between the results obtained by these different methods can provide additional information about a dynamical processes in amorphous systems (for example, about spectral diffusion).
