摘要

In this work, following the crystallochemical analysis and electronic structural parameters of and single crystals, we predicted and experimentally demonstrated the second harmonic generation (SHG) and electrooptics effects for them. Photoinduced changes were performed by using the 7 ns UV nitrogen laser at wavelength 337 nm. The parameters of the SHG were determined through probing in to the reflected regime at wavelength of the 532 nm. The dependence of the output SHG versus photoinducing power density is studied. Explanation of the observed effect is given within a framework of the quantum chemical DFT simulations.
