Persistent holes in the spectra of localized vibrational modes in crystalline solids

Abstract

Persistent nonphotochemical spectral holes have been burnt at low laser intensity in the vibrational absorption line of a spherical-top molecule in alkali halide crystals. These observations complement earlier studies on electronic transitions in organic crystals and glasses and demonstrate that persistent hole burning is a general solid-state phenomenon. © 1982 The American Physical Society.
