“…By using the values of nonlinear refractive index n 2 and nonlinear absorption coefficient β eff , the third-order nonlinear optical susceptibility χ (3) of the undoped and N-doped ZnO thin films were calculated and are shown in table 2. The values of β eff and n 2 that were obtained are larger than those recently reported in literature [27][28][29][30][31][32][33] and are shown in table 3. The z-scan experiments were performed on the plane glass used and no profound contribution was found for the nonlinearities with the input power used.…”

The third-order nonlinear optical properties of undoped and nitrogen-doped ZnO thin films were evaluated using the z-scan technique. The films were sputter-deposited on glass substrates using radio frequency power. The He-Ne continuous wave laser operating at 633 nm was used as an irradiation source. A change in the growth mode in the nitrogen-doped films was observed. The grain size and roughness were found to be dependent on the nitrogen concentration, as shown by atomic force microscopy analysis. The optical band gap was determined and found to increase with nitrogen concentration in the films. Both nonlinear absorption and refraction nonlinearities were exhibited by the deposited films. The nonlinear refractive index n 2 , the nonlinear absorption coefficient β eff and the third-order nonlinear optical susceptibility χ (3) were determined and found to be largest. Multiple diffraction ring patterns were observed when the samples were made to interact with the laser beam and were attributed to refractive index change and thermal lensing. Further, optical power-limiting experiments were performed to determine the optical-limiting threshold and clamping values for undoped and nitrogen-doped ZnO films.

“…Semi-organic single crystals are mainly used for the optical applications hence; the optical transmittance range, transparency, cut-off and the absorbance band are the important parameters to tailor the material for specific device applications [34]. The UV-Vis-NIR optical absorption spectrum of the PHBr crystal recorded in the wavelength range 100-1000 nm is shown in Fig.5a.…”

Bulk size of urea barbituric acid single crystal which have not been reported earlier was successfully grown by slow evaporation solution growth method. Single-crystal XRD brought out the lattice constant and the crystal system is observed to be monoclinic with space group P. Functional group of UBA were determined by FT-IR. Title crystal is entirely visible from 270 to 900 nm with linear optical energy gap value to be 4.50 eV. The observed HOMO-LUMO energy gap was 5.21 eV. Thermally, UBA crystal is found to be stable up to 184˚C. The Cp value of UBA increases from 1.21 to 1.58 J/gK with the temperature difference from 30 to 100˚C. UBA shows good photoconductive nature and it found to be positive and Laser Damage Threshold (LDT) value of UBA crystal is 0.97 GW/cm2. Hardness testing confirms that UBA crystal belongs to soft nature category. Dielectric properties of UBA crystal are studied as a function of frequency and temperature. Third order NLO properties of the UBA crystal were studied under CW and pulsed lasers (ns) regimes using Z-scan technique. Good Optical limiting (OL) response confirms the efficiency of UBA crystal to be used as optical limiters for protection towards short pulse lasers.
