“…In contrast, less research has been reported regarding palladium complexes supported with Schiff base ligands as chromophores in the field of NLO materials. [29][30][31][32] Organic compounds presenting high second-order NLO responses (molecula r hyperpolarizability, β) are generally made of electron-donor group (D) and electron-acceptor group (A) linked through a π-conjugated system to form a D-π-A dipolar push-pull structure. 33 They show effective intramolecular charge transfer from the donor to the acceptor, featuring low-energy and intense charge transfer absorptions.…”

“…The NLA coecients of the synthesized samples were obtained from OA Z-scan in the order of 10 −5 (cm/W) with positive sign that shows the presence of strong saturable absorption (SA) [25]. It is clear that by adding MgO NPs into polymer matrix, the amount of β has increased.…”

The third-order optical nonlinearities of poly (ether) urethane open cell (PEUOC)/MgO nanocomposites, dissolved in dimethylformamide are characterized by Z-scan technique with CW Nd:YAG laser at its second harmonic frequency of 532 nm with TEM00 Gaussian prole. The synthesized samples are also characterized by optical microscopy and scanning electron microscopy imaging. The nonlinear refractive indices and nonlinear absorption coecients of the synthesized samples are obtained in the order of 10 −8 cm 2 /W with negative sign and 10 −5 cm/W, respectively. The origin of optical nonlinearity in this case may be attributed due to the presence of strong saturable absorption eect. All the results suggest that the nonlinear coecients of the synthesized samples can be controlled by nanoparticles content into PEUOC. Furthermore, the results show that PEUOC/MgO may be promising candidate for the application to optical limiting in the visible region.

The third-order optical nonlinearities of polyurethane open cell (PUOC)/MgO nanocomposites, dissolved in dimethylformamide are characterized by Z-scan technique with continuous-wave (CW) Nd:YAG laser at its second harmonic frequency of 532 nm with TEM 00 Gaussian profile. The synthesized samples are also characterized by scanning electron microscopy imaging. The nonlinear refractive indices and nonlinear absorption coefficients of the synthesized samples are obtained in the order of 10 -8 cm 2 /W with negative sign and 10 -5 cm 2 /W, respectively. The origin of optical nonlinearity in this case may be attributed due to the presence of strong saturable absorption effect. All the results suggest that the nonlinear coefficients of the synthesized samples can be controlled by the nanoparticles contents into PUOC. Furthermore, the results show that PUOC/MgO may be helpful candidate for the application in nonlinear optical field in the visible region.
