Bulk zinc selenide crystals doped with different elements have been widely used for the laser emission in the middle IR frequency range. Here, we investigate the influence of iron and iron–neodymium volume and surface doping on the optical transmission properties of ZnSe crystals in the visible and NIR range (400–1000 nm) by the linear absorption s...

High-intensity optical radiation propagation in a transparent dielectric medium causes the phenomena of pulse self-action and radiation generation at triple frequencies due to the cubic nonlinearity of the medium. However, quadratic nonlinear effects usually outshine the cubic ones in anisotropic nonlinear crystals. In this work, we demonstrate tha...

Synthesis of acrylate based nanocomposites for photonic applications were performed, and the influence of gold and chalcogenide glass nanoparticles on optical parameters of nanocomposite layers at high laser intensities was investigated. Whereas the polymerization, recording of optical gratings or other elements and variations of their functional p...
Metal halide perovskite nanocrystals (NCs) attract much attention for light-emitting applications due to their exceptional optical properties. More recently, perovskite NCs have begun to be considered a promising material for nonlinear optical applications. Numerous strategies have recently been developed to improve the properties of metal halide p...
Emerging laser plasma-based technologies require new knowledge on the optical pump optimization and underlying physics of laser-matter interaction. Plasma in liquid jets is still largely unexplored, although this configuration is actively used as a part of optical devices. Hereby, in this work we report on the reflectivity-based approach to study t...
Speckle patterns can be very promising for many applications due to their unique properties. This paper presents the possibility of numerically and experimentally formation of speckle patterns using broadband THz radiation. Strong dependence of the statistical parameters of speckles, such as size and sharpness on the parameters of the diffuser are...

Since chirality is one of the phenomena often occurring in nature, optically active chiral compounds are important for applications in the fields of biology, pharmacology, and medicine. With this in mind, chiral carbon dots (CDs), which are eco-friendly and easy-to-obtain light-emissive nanoparticles, offer great potential for sensing, bioimaging,...
Laser-driven nonlinear phenomena can both reveal the structural features of materials and become the basis for the development of various translated technologies, including highly intense terahertz sources. Here we realize a modified single-color double-pulse excitation scheme for enhancing the terahertz wave generation in flat liquid jets, and we...
Experimental results and theoretical analysis of single-cycle terahertz pulse interaction with cubic nonlinear medium shows that the generation of radiation at triple frequencies disappears. It is replaced by the generation of radiation at quadruple frequencies.
By using subpicosecond terawatt infrared pulses, we demonstrate strong x-rays generation in flat water jet. Varying the pump energy, pulse duration and its chirp along with measuring the angular x-ray distribution, we define the conditions which allow achieving the most intense x-ray emission. The terawatt powers made it possible to reveal two char...
Due to their high resonant third-order nonlinear response, lead sulfide quantum dots (QDs) are potential materials for applications in the field of nonlinear optics. In this paper, we implement the Z-scan method to study the resonant nonlinear response of lead sulfide QDs in colloidal solutions. We managed to measure the purely intrinsic resonant n...
We present the results of a study of milk as a complex biological fluid. The simultaneous occurrence of both direct and reverse sedimentation associated, respectively, with the protein and fat components of milk is demonstrated. Digital holographic interferometry enables the determination of the spatial and temporal changes in the refractive index...
