“…This shows that the samples possess negative nonlinear index with self-defocussing properties. Since, the cw laser source used in the study, the origin of such nonlinearity is attributed to thermal [24]. The absorption of cw laser causes a spatial distribution of temperature in the samples, producing a spatial variation of refractive index.…”

We report the third order nonlinear optical properties of Er 3+ -doped BaMoO4 nanostructures, and its dependence on Er dopant concentration. BaMoO4 nanostructures with different concentration of Er were synthesized by chemical precipitation method and were characterized by UV-Vis absorption, X-ray diffraction (XRD), transmission electron microscopy (TEM) and fluorescence measurements. The incorporation of Er ions shifted the absorption band of BaMoO4 towards higher wavelength and enhanced the light absorption in the visible region.XRD patterns showed that the powders crystallize in scheelite-type tetragonal structure. The nonlinear optical behavior of the nanostructures was investigated by a Z-scan technique at 532 nm using continuous wave Nd:YAG laser. Experimental results suggested that the addition of Er can considerably enhance the nonlinear absorption and refractive index coefficients of BaMoO4 which could be used as a potential for nonlinear optical device applications.

The curcumin analogues (Cur‐MeS and Cur‐MeO) are synthesized using the 3‐chloroacetyl acetone and aromatic aldehydes reaction. Both compounds are characterized using FTIR, LC‐MS, 1H NMR, and 13C NMR spectroscopies. The geometric optimization and thermodynamic properties of the two compounds are carried out theoretically using DFT. The highest HOMO, lowest LUMO, and Mullikan atom charges of the two compounds are calculated using the B3LYP and CAM‐B3LYP methods which are hybrid functionals with a 6‐311+G(2d,p) as the basis set. The nonlinear optical (NLO) properties of both compounds are studied using the spatial self‐phase modulation (SSPM) through the diffraction ring patterns (DRPs) and the Z‐scan techniques, using a continuous wave (cw) low power 473 nm laser beam. The index of nonlinear refraction (INR) of both compounds is calculated by the two techniques. The all‐optical switching property of both samples is tested using two visible cw laser beams.
