AbstractCompounds WCu2OS3(PPh3)4 (I) and MoCu2OS3(PPh3)3 (II) were synthesized by reactions of (NH4)2MO2S2 (M = W, Mo), Cu2S and PPh3 in solid state for nonlinear optical studies. A wide transparent window (λ = 400 - 1000 nm) was observed for both clusters, which makes them attractive for nonlinear optical (NLO) applications. NLO properties of the clusters were studied with a 7-ns pulsed laser at 532 nm. Cluster I exhibits mainly optical self-focusing (n2 = 8 × 10-18 m2 W-1, as measured with an 1.2 × 10-4 M acetonitrile solution) with negligibly small nonlinear absorption. Cluster II exhibits both optical self-focusing (n2 = 5 × 10-17 m2 W-1, as measured with a 7.4 × 10-5 M acetonitrile solution) and nonlinear absorption (α2 = 2.6 × 10-10 m W-1). The third-order NLO susceptibilities (χ(3)) of the two clusters at the above-mentioned concentrations are 2 × 10-11 esu for I and 1.2 × 10-10 esu for II respectively. These nonlinear optical properties of the clusters were compared with those of cubic cage shaped and nest shaped clusters to reveal a qualitative structure/NLO property correlation.

AbstractIn this study, we present a systematic study of linear and nonlinear optical properties of Para Red with the aim of Z-scan technique and quantum mechanical calculations. The Z-scan experiments were performed using a 532 nm Nd: YAG (SHG) CW laser beam. Para Red exhibited a strong nonlinear refractive index, nonlinear absorption coefficient and third-order nonlinear susceptibility 3.487 × 10−6 cm2/W, 2.341 × 10−1cm/W and 2.157 × 10−4 esu, respectively. Also, quantum chemical analysis was used for the calculation of the dipole moment μ, dipole polarizability α, anisotropy of polarizability Δα and molecular hyperpolarizabilities (β,γ). The results revealed that Para Red has large first and second hyperpolarizabilities. However, from the obtained results, it was found that Para Red can be a promising material for applications in the development of non-linear optical materials.

In this work, the photo-physical properties of seven different phthalocyanine derivatives are studied, with a focus on their transparency spectral range. Two compounds among them are recently synthesised. The investigations include synthesis, photoluminescence, absorptive and refractive nonlinear properties, and optical limiting performances. The compounds are found to be emitting interesting broad fluorescence bands in the visible range. The nonlinear optical properties are investigated with the help of Z-scan technique, with both a continuous laser at 488, 514.5 and 632.8 nm, and with a pulsed laser at 532 nm. The sign and the magnitude of the nonlinear refractive index, third-order susceptibility, and nonlinear absorption coefficient have been evaluated in the seven compounds. The optical limiting performance of each compound was also evaluated in the continuous and pulsed laser excitation regimes. Keywords:

In this study, 8-(4-methoxyphenyl)-6-oxo-3-p-tolyl-6H-pyrido[1,2-b][1,2,4]triazine-7,9-dicarbonitrile (A) was prepared and then the nonlinear optical properties of this compound, including nonlinear refractive index (n2) and nonlinear absorption coefficient (β) were measured using Z-scan technique by continuous wave laser diode at wavelengths of 405 and 532 nm. At wavelength of 532 nm, by increasing the incident intensity a switch over from saturable absorption (SA) to reverse saturable absorption (RSA) was observed. The results showed that the nonlinear optical properties of this compound depend on the wavelength. It was also observed that with decreasing incident intensity, the thermal nonlinear refractive coefficient increased accordingly, while its thermo-optic coefficient decreased. In addition, the third-order susceptibility of this compound in wavelength of 532 nm was obtained higher than 405 nm.

We have synthesized highly stable silver nanoparticles in aqueous solution at room temperature by standard reduction method using bovine serum albumin (BSA) as a stabilizing agent. The nonlinear optical properties of nanoparticles were investigated using Z-scan technique at 532 nm. The obtained nonlinear absorption coefficient and negative nonlinear refractive index is found to be 88.36 cm/GW and -5.1 × 10-7 esu respectively. The real and imaginary part of third order susceptibility of silver nanoparticles is found to be 1.553 × 10-7 esu and 0.7 × 10-7 esu respectively. The silver nanoparticles in BSA template show good optical limiting property.
