Abstract
The mechanism behind the propagation of a slow wave of changes in reflectio n and conductivity (WCRC) excited by an infrared laser radiation pulse is i nvestigated experimentally and theoretically. It is demonstrated that two d ifferent (rising and falling) temperature dependences of the WCRC velocity, observed in experiments performed with different materials, can be qualita tively described in terms of the theory of a slow wave of recombination of laser-induced defects.
