“…The b value of the novel DMMA crystal was evaluated with the aid of the standard equation, where del T is the difference between the maximum of The thermal effects arising from the continuous wave laser and the excited state absorption (ESA) make the greatest contributions to the RSA. 77 The formula below was used to calculate the theoretical open aperture plot. The experimentally obtained open-aperture curve and theoretically simulated open-aperture graph are shown in Fig.…”

“…As a result, the development of such materials has become a significant focus in research endeavors. [5][6][7] Porphyrin, as a small organic molecule with a large π-conjugated structure, has a wide spectral response range, fast response rate, and large non-linear absorption coefficient, showing good prospects for applications in fields such as non-linear optics. [8] As a semiconductor material, titanium dioxide (TiO 2 ) has the advantages of high transmittance in the visible to infrared region, stable physicochemical properties, high refractive index, and many carriers.…”

A combination of organic and inorganic components was used to synthesize the nanocomposites TCPP-SSA-P25-PMMA, which involved connecting porphyrin and TiO 2 . These nanocomposites were then used to create optical devices with practical uses. The Z-scan technique was employed to investigate the nonlinear optical properties of the material. The results demonstrated that TCPP-SSA-P25-PMMA possesses outstanding nonlinear optical properties, with a value of 2.5 × 10 -9 m/W and an Im[χ (3) ] of 15.8 × 10 -11 esu. TCPP-SSA-P25-PMMA was incorporated into a poly (methyl methacrylate) (PMMA) matrix to produce TCPP-SSA-P25-PMMA/PMMA optical plastic, which exhibited improved third-order optical nonlinearity, with a value of 5.1 × 10 -9 m/W and an Im[χ (3) ] of 1.68 × 10 -10 esu. Furthermore, it displayed a dynamic range of 0.4 and a minimum transmittance of 0.4. These enhancements were attributed to the suppression of the porphyrin group's aggregation effect on TCPP-SSA-P25-PMMA in the solid matrix. As a result, the nanocomposite has substantial potential for practical applications.

“…There has been considerable interest in the development of highly efficient nonlinear optical organic salt crystals due to their potential applications in high-speed optical modulators, field detectors, frequency conversion, and terahertz wave generation. − In particular, salts in which the cation has been designed to have a large molecular hyperpolarizability and where the counterion variation enables the creation of crystals featuring the necessary noncentrosymmetric packing. For instance, one highly polar organic nonlinear optical (NLO) crystals, 4- N , N -dimethylamino-4′- N ′-methyl-stilbazolium tosylate (DAST), based on strong Coulomb interactions to achieve noncentrosymmetric crystalline packing, exhibited an second harmonic generation (SHG) efficiency 1000 times greater than of urea, a standard NLO compound .…”

Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) have been used to investigate the nonlinear optical (NLO) properties of phenolic N-pyrimidinyl stilbazolium cationic chromophore in its corresponding noncentrosymmetric crystals. Such a cationic chromophore, the OPR (4-(4-hydroxystyryl)-1-(pyrimidin-2-yl)pyridinium), consists of a strong electron donor, the 4-hydroxyphenyl group, and a strong electron acceptor, the N-pyrimidinylpyridinium group based on two electronwithdrawing groups. The in-crystal NLO properties were determined by applying a supermolecule approach in combination with an iterative electrostatic scheme, in which the surrounding molecules of a unit cell are represented by point charges. With CAM-B3LYP, our absolute estimates for the largest diagonal component of the second-order nonlinear susceptibility tensor of OPR-based crystals range from 64.00 to 80.34 pm/V in the static regime and from 162.09 to 175.52 pm/V at 1907 nm. These values are significant when compared to those of benchmark stilbazolium-based crystals. Furthermore, the third-order susceptibility, which is related to the nonlinear optical process of the intensity-dependent refractive index, is also significant compared to the results for other organic crystals, such as chalcone derivatives. With TD-CAM-B3LYP, the two-state model effectively explains the similarity in the first hyperpolarizability values in the crystalline phase. This similarity arises from the combination of the oscillator strength and the charge transfer of the crucial transition. Therefore, phenolic organic salt crystals show great promise for various nonlinear optical applications.
