“…A vast amount of research has been devoted towards the study of organic materials, inorganic materials, etc, nonlinear optical (NLO) properties for the sake of using them in a variety of applications, viz., image processing, optical communications, limiting, 3D data storage, phase conjugation, switching, and bi-stability [1][2][3][4][5][6][7][8][9][10][11][12]. In these applications the nonlinear refractive index (NLRI), n 2 , of materials must be large and their response time must be short.…”

The synthesized Schiff base ligand (compound Z1) is analyzed by IR, mass, 1HNMR, and 13CNMR spectroscopies. Computational chemical modeling is performed to examine the geometry optimization and molecular structure of compound Z1 by using the DFT/ WB97XD/6-31+G(d,p) method. The parameters HOMO-LUMO energies with nonlinear optical (NLO) properties are computed. The results indicate good agreement cor-relations of experimental and theoretical data so that compound Z1 prove to have good NLO properties. The NLO properties of the compound Z1 are examined under excitation with a 473 nm, cw, low power laser beam via two techniques viz., diffraction patterns (DPs) and the standared Z-scan techniques. The nonlinear refractive index (NLRI), n2, of compound Z1 is estimated by the two techniques were as high as n2 value of 3.03×10-11 m2/W is obtained at the maximum power input due to the DPs. Both static and dynamic all –optical switching (SAOS and DPOS) are tested using 473 nm and 532 nm cw low power laser beams.

“…These properties have a number of applications in the photonics field and optical devices. The materials which possess high nonlinear optical properties, NOPs, and fast response times proved that they can be used as optical limiting [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], optical switching [22][23][24], optical phase conjugation [25], optical bi-stability [26][27][28][29], optical data storage [30][31][32][33], etc. So before we test the possibility of using the material in any of these applications we must first study the NOPs of the material.…”

Diffraction patterns and Z-scan methods are used to measure the nonlinear refractive index, NRI, of the eosin methylene blue in the solvent ethanol using a continuous wave laser beam of 473 nm wavelength. Experimental results of the former and latter methods showed the appearance of rings and the self-defocusing SDF effect respectively, and these results may be due to phase modulation. It is demonstrated that the eosin methylene blue solution have a high NRI. Also the limiting optical properties of the sample are investigated. It is observed that the sample has the optical limiter properties OLPs. It is proved that the origin of the OLPs is thermal. The NRI and threshold limiting values of the eosin methylene blue solution are −1.1 × 10−8 cm2 W−1 and 12 mW, respectively. A thermal lens model and the Fresnel–Kirchhoff integral are used to calculate the self-defocusing and the diffraction ring patterns results respectively.
