Dispersion characteristics of bulk single-domain and periodically poled Nd:Mg:LiNbO3 crystals are measured in the transparency region (with the accuracy 0.0002) and for the upper phonon polariton branch (with the accuracy 0.0030.05), from 0.44m up to 10.5m. The method of spontaneous parametric light scattering is used for measurement of the ordinary refractive index dispersion in the mid-infrared...
We report the results of the experimental study of the four-wave polariton scattering in LiNbO 3 . Different types of scattering processes and their mutual influence are considered. Analyzing the angular dependences of the scattering intensity, we show that the cascade coherent type of interaction is predominant in LiNbO 3 . Perspectives of the measurement of refractive indexes...
