Summary: This study investigated the nonlinear optical properties of silver nanoparticles (AgNPs) using the Z-scan method, and examined their dependence on excitation wavelength, AgNP concentration, and size. The results showed that both the nonlinear refractive index (n(2)) and nonlinear absorption coefficient (alpha(3)) of AgNPs increased with increasing concentration. However, n(2) and alpha(3) decreased with increasing excitation wavelength and average size of the AgNPs.

Summary: Optical tweezers can stably trap submicron particles on black-Ti surfaces using low-intensity focused light, demonstrating optically driven and reversible trapping behavior. The Ti nanostructures were shown to play a key role in this trapping technique as trapping was not observed on nonstructured Ti or nanostructured silicon surfaces.

Summary: Concentration, morphology and composition-dependent thermal diffusivity changes in bimetallic AuAg nanoparticles synthesized by femtosecond laser ablation were studied using a matched thermal lens technique. Thermal diffusivity values increased with both sample concentration and Ag/Au weight percentage ratio. Core-shell and nanoalloy structures showed greater thermal diffusivity variation, possibly due to modified surface state density of the bimetallic nanoparticles. Nonlinear optical characterization using a Nd:YAG laser showed a switching behavior from saturable absorption to reverse saturable absorption as the ablation time increased. The optical limiting properties of the nanoalloy were also studied.

Summary: The research presents the outcomes of extensive femtosecond nonlinear optical studies on TiO2 and Ag-doped TiO2 nanoparticles. It was observed that Ag-TiO2 nanoparticles exhibited a significant preference for three-photon absorption and had a higher nonlinear susceptibility compared to pure TiO2 nanoparticles under 1 kHz pulse excitation. Additionally, the synthesized nanocomposites showed a noteworthy presence of three-photon absorption in the near-IR regime, which is a rare observation in these types of nanoparticles.

Summary: The third-order nonlinear optical properties of aqueous methyl blue solution are investigated using the Z-scan method with 800 nm fs radiation. The magnitudes and signs of the nonlinear refractive index n2, the nonlinear absorption coefficient β, and the third-order nonlinear optical susceptibility χ(3) are determined. The values of β and n2 are found to be in the order of 10-13 m/W and 10-20 m2/W respectively. All the calculated nonlinear optical parameters exhibit linear dependence on the sample concentration. The open aperture Z-scan shows reverse saturable absorption, while the closed aperture transmittance reveals the self-defocusing effect and the negative refraction nonlinearity. The results suggest that methyl blue has potential for photonic applications.

Summary: The study found that a DC magnetic field in the range of 0-180 mT has significant effects on the properties of cobalt oxide nanoparticles synthesized by pulse laser ablation in distilled water. Increasing the magnetic field strength during the ablation process resulted in a noticeable decrease in the size of the nanoparticles, leading to a shift in their excitonic absorption peaks. By applying an external magnetic field, crystalline structure nanoparticles were obtained, while in the absence of an external magnetic field, only amorphous phase nanoparticles were produced. The results suggest that an external magnetic field is a strong tool for controlling the properties of ferromagnetic nanoparticles produced by laser ablation.

Summary: Mn3O4 (hausmannite) nanoparticles were synthesized using the pulsed laser ablation method in a liquid environment and deposited on an aluminum substrate using the direct current electrophoretic deposition technique. The effects of deposition voltage and time on the film characteristics were studied using various diagnostic methods. The formation of stable manganese oxide nanoparticles with the chemical formula Mn3O4 was confirmed by X-ray diffraction, and the morphology of the films changed from spherical nanoparticles to nanosheets with increasing deposition voltage. The roughness, average particle size, and thickness of the deposited thin films could be controlled by the applied voltage and deposition time, as observed by AFM studies. Additionally, the reflectance patterns of the samples depended on the material of the thin films and substrates, as well as the size of particles in the film structure, as indicated by UV-Vis-NIR spectroscopy results.

Summary: The experiment investigates the influence of a transverse magnetic field on plasma plume produced by pulsed laser ablation as well as the structural and optical properties of nickel oxide nanoparticles. The strength of the external magnetic field can be controlled by the distance between magnets. Results show that increasing the strength of the magnetic field leads to an increase in XRD peak intensity and a decrease in particle size. Additionally, the magnetic field causes cyclotron motion of charged particles in the plasma plume, increasing their energy and reducing agglomeration.
