“…The two nonlinear interactions that can be determined in this fashion are the sample's nonlinear index of refraction and nonlinear absorption coefficient (Sheik-Bahae & Hasselbeck, 2000). To detect the nonlinear properties as the absorption coefficient and the nonlinear refractive index, there are two methods, each of which is calculated as one of them depending on the other : (i) The geometry in which a finite aperture is kept before the detector is known as a closed-aperture (CA) Z-scan; (ii) the geometry in which the aperture is removed to focus all the transmitted light into the detector is referred to as an open-aperture (OA) Z-scan (Costela et al, 1996;Hutchings, Sheik-Bahae, Hagan, & Van Stryland, 1992;Chari et al, 1996). The main principle of zscan technique is based on transforming the phase distortion to amplitude distortions during beam propagation (Sheik-Bahae, Said, & Van Stryland, 1989).…”

“…Organic materials [1], including natural dyes [1][2][3] with large NLO responses, are of major interest for their potential applications in optical signal-processing devices, upconversion lasers [4], optical limiting for photo-sensors and human eyes protection from intense laser irradiation [5][6][7][8]. Additionally, materials with NLO properties such as broadband spectral response and fast response time are of great importance for realizing optical data storage [9,10], two-photon microscopy [11] and three-dimensional optical storage micro-fabrication [12].…”

International audience

We report on the optical performances of laccaic acid dye in solution at different concentrations and dye–poly(methyl methacrylate) composite thin films. The linear spectral characteristics including optical constants, i.e. refractive index (n) and extinction coefficient (k), were carried out in a comprehensive way through absorbance, fluorescence and ellipsometric studies. The nonlinear optical parameters such as nonlinear absorption coefficient β eff (or β 2), the imaginary third-order susceptibility (Im[χ (3)]) and the imaginary part of second-order hyperpolarizability (γ) of the samples were evaluated using the open-aperture Z-scan technique with a laser pulse duration of 10 ns at 532 nm wavelength. The corresponding numerical values of these parameters were of 10−10, 10−11 and 10−32 order, respectively. Two-photon absorption was revealed to be the main driving physical mechanism in the nonlinear response. This suggests that laccaic acid dye can be a potential candidate for NLO materials application.

Optical Limiting Behavior of Acid Blue 29 under a Low Power CW He-Ne Laser Irradiation

et al. 2009

View full text Add to dashboard Cite

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.
