“…During the past four decades, the search for materials possessing high nonlinear optical properties is a continuous issue due to their importance. Materials that have high nonlinear optical properties shows efficient performances in various photonic applications, viz., data storage [1,2], optical bistability [3], optical switching [4], optical limiting [5][6][7], optical phase conjugation [8] etc. Most of these applications depends on the third-order nonlinear optical susceptibility, χ (3) , ( the real and imaginary parts), the nonlinear refractive index, n 2 , and the nonlinear absorption coefficient, β.…”

The effect of gamma, γ, radiation on the surface morphology and the optical properties of a prepared alpha-methyl curcumin: PMMA film were studied under different doses (7, 14, 21 and 28 Gy) of γ-rays emitted by 137Cs source. To monitor the effect of γ radiation on the prepared sample, the UV–visible absorbance and transmittance measurements of the pristine and the irradiated sample were carried out in the spectral range 400–900 nm at room temperature. An optical microscope and image J software were utilized to examine any changes in the surface morphology for the pre and post irradiated samples. The obtained results indicated that the surface morphology, linear and nonlinear optical properties of the films have been affected by γ radiation.

“…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.

“…We hope, through the current study, to complete our previous series of works that started ten years ago, during which we have introduced many materials that could be used in various photon applications [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59]. Therefore, one of the dyes of the azo family, called Eriochrome Black T, EBT, was chosen as a sample in this study, which according to our knowledge has not previously been tested for the sake of obtaining its linear and nonlinear optical parameters.…”

Eriochrome Black T doped polyvinyl alcohol film was prepared on a glass substrate via the casting method. Optical microscope image of the film was taken by an optical microscope and analyzed by an Image J and origin 2008 software where it was proved that the film was free of defects and holes and uniformly distributed over entire area of the substrate. The optical constants of the film were calculated via the optical absorbance and transmittance in the wavelength range 350–900 nm via the use of a set of known mathematical formulas together with Wemple and DiDomenico model. The optical conductivity and the electrical conductivity of the prepared film in response to external electric filed are obtained using two more equations where it was found that the prepared film have high optical conductivity of the order of 1012 s−1 and an electrical conductivity of the order of 104 (S cm−1).
