Popis:	The large growth of the absorption of radiation with doubled frequency in a region of high values for the induced electric fields has been detected during the investigation of an optical poling process in germaniumsilicate glass. The absorption suppresses the writing of the second-order susceptibility grating and leads to restriction of the maximum efficiency of the photoinduced second-harmonic generation in the glass.
