The third-order nonlinear optical properties of C_{60}/poly(dimethylacetylendicarboxylate) have been studied using Z-scan technique. Experiments are performed using a CW diode laser at 635 nm wavelength and 26 mW power. The nonlinear absorption coefficient β, nonlinear refractive index n₂, Reχ³, and Imχ³ in C_{60} doped poly(dimethylacetylendicarboxylate) are measured using Z-scan data. Our results show that the values of the nonlinear optical parameters (β, n₂, Reχ³, and Imχ³) of C_{60} doped poly(dimethylacetylendicarboxylate) are smaller than the polymer itself.

The third-order nonlinear optical properties of 1,1'-methylenedipyridinium bis[tetrachloride gold(III)] were investigated by the z-scan method using CW diode laser. The experimental results led to estimation of the nonlinear optical absorption coefficient (β), the nonlinear optical refraction (n₂), and third-order nonlinear optical susceptibility (χ³). Our results show that the excited-state absorption cross-sections (σ_{ex}) is larger than the ground-state absorption cross-sections (σ_{g}), this suggests that the nonlinear optical absorption in the MPTC gold(III) is due to the reverse saturable absorption mechanism. Furthermore, the obtained results suggest that our material is considered as a promising candidate for future optical devices applications.

Optical limiting performances of acid blue 29 are investigated under irradiation by a 35 mW continuous wave He-Ne laser. The optical limiting behavior is investigated by using transmission measurement through samples with different concentrations. Our results show that the optical limiting efficiency is concentrations dependence. Induced self-diffraction patterns are observed at relatively high intensities starting from 15 mW.
