Abstract:
Third-harmonic generation experiments have been performed on fully oriented crystalline ItransR-(CH)x Rat two laser wavelengths: 1.064 and 1.907 m. Theoretical analysis of third-harmonic generation in a semiconductor slab is presented which allows the extraction of the electronic third-order susceptibility from the experiments. A simple method was used for the elimination of environmental effects on the measurements. The third-order susceptibilities obtained are xxxx(3) =1.064m=(94) ×10-9 esu and xxxx(3) =1.907m =(1.70.7)×10-8 esu, representing exceptionally high values compared to other organic and inorganic semiconductors.
