“…It may differ from the final official version of record. 6 The nonlinear refractive index, n 2 , can be evaluated from the peak-to-valley transmittance difference, ∆T p-v , which is linearly related to the on-axis phase distortion, ∆Φ 0 , of the radiation passed through the sample [12]. The relations are defined as:…”

In this experimental work, nonlinear optical properties of Oxazine 720 laser dye in acetone, dimethyl sulfoxide, ethanol, and water were studied using z-scan method. It is found that the nonlinear behavior of Oxazine 720 dye in water is different from other organic solvents. The magnitude of nonlinear refractive index was obtained in the order of 10 -8 cm 2 /W and 10 -7 cm 2 /W for the 0.2 mM solutions of this dye in water and other solvents, respectively. Also, it was observed that in the aqueous solution reverse saturation absorption occurs while in other organic solvents, saturation absorption occurs and near the focal point of the lens, it is converted to reverse saturation absorption. These differences in the nonlinear refractive index and nonlinear absorption changes of aqueous solution and other solutions can be due to strong aggregative behavior of dye molecules in water.

“…The grown crystal of KAP is one of the potential materials for second harmonic generation (SHG) applications and its efficiency is 1.13 times higher than that of standard Potassium Dihydrogen Orthophosphate (KDP) single crystal [34]. In addition to the above said property, it also obeys the third order nonlinear optical behavior which is measured by Z-scan technique which is a simple and famous experimental method for the precise measurements of intensity dependent nonlinear susceptibilities, nonlinear refractive index and the nonlinear absorption (NLA) coefficient and based on the principles of spatial beam distortion [35][36][37][38]. It is a single-beam method employed to find out the real and imaginary parts of nonlinear optical susceptibility of a material.…”

A good optical quality semi-organic single crystal of Potassium Acid Phthalate (KAP) was harvested from aqueous solution by using slow evaporation solution growth technique (SEST) at ambient condition. The defect free single crystal of KAP was analyzed by different instrumentation techniques, for checking its compatibility for different applications. Its unit cell dimensions and phase purity was examined by powder X-ray diffraction (PXRD) and found that it crystallizes in orthorhombic with non-centrosymmetric in nature. The quality of the grown ingot was assessed by high resolution X-ray diffraction (HRXRD) technique and found that, the crystalline quality is better with less grain boundaries. Its optical properties were scrutinized by UV-vis., photoluminescence (PL) and time resolved photoluminescence (TRPL) measurements respectively. The mechanical stability of the grown crystal was tested by Vickers microhardness method and found that the grown crystal shows indentation size effect (ISE) which was explained using different theoretical models. Its third order nonlinear optical properties were studied by Z-scan measurement by using Ti:Sapphire laser as a source and determined its nonlinear absorption coefficient (β) and it was found that the KAP crystal is one of the preferable choices for optical limiting applications.

The third‐order susceptibility of lithium niobate (LiNbO3) is calculated within a Berry‐phase formulation of the dynamical polarization based on the electronic structure obtained within density‐functional theory (DFT). Maximum values of the order of m V are calculated for photon energies between 1.2 and 2 eV, i.e., in the lower half of the optical bandgap of lithium niobate. Both free and bound electron (bi)polarons are found to lead to a remarkable enhancement of the third‐order susceptibility for photon energies below 1 eV.
