“…This is caused by a necessity to know how the optical limiting and self-focusing effects may influence the second order optical properties, first of all the second harmonic generation. This is particularly important when the photoinduced effects are used at different wavelengths [7]; and for the photoinduced electric polarizability [8]. As a consequence, in the present work we carry out explorations of the third-order optical features such as two-photon absorption (TPA) and nonlinear optical refractive index (n 2 ) using the Z-scan technique.…”

The Z-scan measurements for the non-centrosymmetric optical crystals β-BaTeMo 2 O 9 (BTMO) were performed. The corresponding experiments were carried out using the 5 ns pulses of the second harmonic of a nanosecond Nd:YAG laser at the 532 nm wavelength. It was shown that the studied crystals possess promising third-order optical susceptibilities, which allow to use the crystal as optical limiters. The comparison with other oxide materials is presented. To clarify the origin of the observed effect, the electronic and optical properties of BTMO were calculated using the density functional theory (DFT)-based method. The performed calculations of the electronic and optical properties revealed certain peculiar features that can be suitable for the non-linear optical applications. The relation between the observed nonlinear optical features and the calculated band structure is emphasized. The values of the calculated band gap and refractive index for β-BaTeMo 2 O 9 are also reported.

An emerging area in condensed matter physics is the use of multilayered heterostructures to enhance ferroelectricity in complex oxides. Here, we demonstrate that optically pumping carriers across the interface between thin films of a ferroelectric (FE) insulator and a ferromagnetic metal can significantly enhance the FE polarization. The photoinduced FE state remains stable at low temperatures for over one day. This occurs through screening of the internal electric field by the photoexcited carriers, leading to a larger, more stable polarization state that may be suitable for applications in areas such as data and energy storage.
