Abstract

The technique of persistent spectral hole burning provides a sensitive tool for examining slow relaxation processes in amorphous solids. Photochemical holes relax on a logarithmic timescale. Temperature cycle experiments lead to irreversible hole filling and broadening. This behaviour can be understood within the frame of two level systems. The dispersion of relaxation rates and the distribution of barrier heights can be determined.
