Item Effect of incorporated metal oxides nanoparticles on quadric and cubic nonlinear optical response of the single crystal KDP matrix(Видавництво Львівської політехніки, 2012) Brodyn, M.; Gayvoronsky, V.Efficient impact of the incorporated metal oxides nanoparticles on self-action effects and optical harmonics generation was studied in single crystalline KDP matrix. It was shown possibility to enhance laser frequency conversion efficiency due to the anatase giant optical response manifestation.Item Impact of self-action effects on second harmonic generation efficiency in KDP crystals with embedded anatase nanoparticles(Видавництво Львівської політехніки, 2012) Popov, A.; Yatsyna, V.; Kopylovsky, M.; Pritula, I.; Gayvoronsky, V.Second harmonic generation efficiency enhancement in KDP single crystals with embedded anatase nanoparticles was accomplished in comparison with nominally pure KDP crystal. The enhancement effect occurs due the self-focusing of laser pump pulses.Item Linear and nonlinear refractive index modifications in pHEMA-oxo-TiO2 hybrids studied via cw-UV laser excitation and self- action of picosecond laser pulses(Видавництво Львівської політехніки, 2012) Uklein, A.; Gayvoronsky, V.; Gorbovyi, P.; Museur, L.; Kanaev, A.; Brodyn, M.Linear and nonlinear optical properties of pHEMA-oxo-TiO2 nanohybrids were studied. The reduction of refractive index with the increase of UV irradiation dose was observed. The TiO2 nanoparticles concentration strongly affects the nonlinear optical response of the composite system.Item Optical and Nonlinear Optical Characterization of Nanosized ZnO(2017-05-29) Multian, V.; Uklein, A.; Boldyrieva, O.; Lisnyak, V.; Gayvoronsky, V.; Institute of Physic of National Academy of Science of Ukraine, 46 Prospect Nauky, 03028 Kyiv, Ukraine; Taras Shevchenko National University of Kyiv, Chemical faculty, 62a Volodymyrska Str., 01601 Kyiv; UkraineItem Self-action effects in KDP single crystals with incorporated aluminum oxyhydroxide nanoparticles(Видавництво Львівської політехніки, 2012) Yatsyna, V.; Kopylovsky, M.; Pritula, I.; Kosinova, A.; Gayvoronsky, V.Optical and nonlinear optical properties of grown KDP single crystals with incorporated aluminum oxyhydroxide nanoparticles were studied. The presence of embedded nanoparticles leads to the change of nonlinear optical response of the composite material relatively to KDP one.Item The influence of xylenol orange dye on nonlinear optical properties of KDP crystals(Видавництво національного університету “Львівська політехніка”, 2009) Pritula, I.; Kosinova, A.; Gayvoronsky, V.; Gromov, Yu.; Kopylovsky, M.; Kolybaeva, M.; Puzikov, V.
