Abstract

The profile of a persistent spectral hole can be used to very sensitively detect induced broadening processes that are caused by infrared radiation absorbed in the host matrix /1,2/. Both, the hole area and the hole width are affected to an extent which depends on the frequency of the irradiated IR-light. The excitation of specific vibrations in the host matrix leads to the observed broadening and filling phenomena of a hole spectrum which are highly selective with respect to different vibrational modes.
