Experimental and theoretical studies of NLO properties of organic–inorganic materials base on p-nitroaniline

Correlation between structural studies and third order NLO properties of selected new quinolinium semi-organic compounds

“…One can also notice the good agreement between the results obtained using THG and DFWM techniques. These values are comparable with the one characteristic of other semi-organic materials [21,22].…”

“…Recently, we have reported on the origin of the nonlinear optical response showing that the nonlinear susceptibility of third-harmonic generation is related not only to the number of the p-conjugated systems but also to the following factors: solvent molecule effects and hydrogen bonds interactions that generate partial charges on the hydrogen atoms which increase significantly the dipole moment of molecules [21,22].…”

Z-scan and optical limiting properties of Hibiscus Sabdariffa dye

“…More precisely, the coefficient of the intensity-dependent refractive index n 2 (n = n 0 ? n 2 I) [12][13], the real and imaginary components of the 3rd order nonlinear susceptibility v (3) as well as the optical limiting thresholds are presented.…”

Treatment of nonlinear optical properties due to large amplitude anharmonic vibrational motions: Umbrella motion in NH3

“…Nonlinear optical 1 processes play an important role in scientific and technological fields such as materials science, communications, and medicine. 2 At the molecular level both the electronic and nuclear degrees of freedom can interact with an electromagnetic light wave and, as a result, nonlinear optical ͑NLO͒ properties contain both electronic and vibrational contributions.…”
