This review gathers the hyperpolarizabilities of monomeric azo dyes studied by various
analytical techniques-electric-field-induced second-harmonic generation (EFISHG), hyper …

Various techniques to characterize the nonlinear (NL) optical response of centro-symmetric
materials are presented and evaluated with emphasis on the relationship between the …

We report here the studies on third-order nonlinear optical properties of two novel
polythiophene composite films investigated using the Z-scan technique. The measurements …

An experimental investigation of the third-order nonlinear optical properties of new poly {2-{5-
[3, 4-ditetradecyloxy-5-(1, 3, 4-oxadiazol-2-yl) thiophen-2-yl]-1, 3, 4-oxadiazol-2-yl} …

We report the measurements of the third-order nonlinear optical properties of recently
synthesized and characterized two different 1, 3-disubstituent chalcones doped PMMA films …

Lanthanum titanate glasses (17 La 2 O 3-83 TiO 2) are fabricated via aerodynamic levitation
melting. Nonlinear refraction and absorption were measured with the Z scan technique …

We show that direct measurement of the beam radius in Z-scan experiments using a CCD
camera at the output of a 4f-imaging system allows higher sensitivity and better accuracy …

The first theoretical prediction of a simultaneous two-photon absorption (TPA) event was
reported by Maria Göppert-Mayer in 1931 [1]. The development of high-energy pulsed lasers …

The intensity-dependent refractive index n 2 and the nonlinear susceptibility χ (3) of Hibiscus
Sabdariffa dye solutions in the nanosecond regime at 532 nm are reported. More presicely …

The close aperture z-scan experiment was carried out using Fresnel–Kirchhoff diffraction
theory, and the special shape of close z-scan curves is determined based on the properties …
