“…Azo-dyes 121 – 123 (Chart ) were exposed to a 532 nm CW laser for the determination of η 2 (comprised between −0.54 and −1.09 × 10 –8 cm 2 /W) and of χ (3) (comprised between −2.15 and −4.35 × 10 –7 esu) . Dye 124 , also named acid blue 29, was investigated, in different solvents, using a CW He–Ne laser beam at 632.8 nm wavelength and 35 mW of output power. − The experiments showed that the OL effect of the solutions of dye 124 (Chart ) becomes stronger for the samples with high polarity solvents, methanol or ethanol being the best solvents. The corresponding limiting thresholds of the solution with different alcoholic solvents were 3 and 4 mW for methanol and ethanol, respectively.…”

The control of luminous radiation has extremely important implications for modern and future technologies as well as in medicine. In this Review, we detail chemical structures and their relevant photophysical features for various groups of materials, including organic dyes such as metalloporphyrins and metallophthalocyanines (and derivatives), other common organic materials, mixed metal complexes and clusters, fullerenes, dendrimeric nanocomposites, polymeric materials (organic and/or inorganic), inorganic semiconductors, and other nanoscopic materials, utilized or potentially useful for the realization of devices able to filter in a smart way an external radiation. The concept of smart is referred to the characteristic of those materials that are capable to filter the radiation in a dynamic way without the need of an ancillary system for the activation of the required transmission change. In particular, this Review gives emphasis to the nonlinear optical properties of photoactive materials for the function of optical power limiting. All known mechanisms of optical limiting have been analyzed and discussed for the different types of materials.

“…On the other hand, such high values of the third-order nonlinearity might be within reach of available materials. For instance, values on the order of χ (3) ~ 10 −15 –10 −13 m 2 /V 2 have been measured in organic dye molecules in the visible range 51 52 . Therefore, the use of organic molecules appears a promising route for the experimental observation of plasmon blockade.…”

We report theoretical evidence that bulk nonlinear materials weakly interacting with highly localized plasmonic modes in ultra-sub-wavelength metallic nanostructures can lead to nonlinear effects at the single plasmon level in the visible range. In particular, the two-plasmon interaction energy in such systems is numerically estimated to be comparable with the typical plasmon linewidths. Localized surface plasmons are thus predicted to exhibit a purely nonclassical behavior, which can be clearly identified by a sub-Poissonian second-order correlation in the signal scattered from the quantized plasmonic field under coherent electromagnetic excitation. We explicitly show that systems sensitive to single-plasmon scattering can be experimentally realized by combining electromagnetic confinement in the interstitial region of gold nanodimers with local infiltration or deposition of ordinary nonlinear materials. We also propose configurations that could allow to realistically detect such an effect with state-of-the-art technology, overcoming the limitations imposed by the short plasmonic lifetime.

“…Alsous et al 25 studied acid blue 29/ethanol solutions, using a CW He-Ne laser at 632.8 nm, and showed that  varies as follows: 10.51×10 -3 , 26.7×10 -3 , and 30.49×10 -3 cm/W at the concentrations 5×10 -5 , 7×10 -5 , and 8×10 -5 M, respectively. Similarly, Mohammed Ali and Palanisamy 26 showed that  value of Basic Green 1 dye at the concentration of 5×10 -5 M (using a CW He-Ne laser at 632.8 nm) was found to be 1.7×10 -3 cm/W.…”

The absorption performance and evolution of the organic dye disperse blue 1 (DB1) in dioxane at different concentrations was investigated. The nonlinear absorption coefficient has been measured through the open aperture Z-scan technique, whose values increased exponentially from 0.997×10 -3 to 11.7×10 -3 cm/W as the dye concentration increased from 3.7×10 -5 to 74.6×10 -5 M. Also, DB1 optical power limiting characteristics appeared at high laser light intensities, whereby very dilute solution of the order of ~10 -4 M was sufficient to limit the transmitted power of the incident laser light by ~90%.
