The influence of cerium impurities on the efficiency and the rates of formation and decay of the photoinduced second harmonic generation in lead-containing glasses based on barium metaphosphate is experimentally investigated. It is shown that introduction of 1.5 mol % of cerium dioxide into the initial glass leads to a substantial gain in the generation efficiency and an increase of at least two orders of magnitude in the dark decay time of the induced quadratic susceptibility. |
