Studying the nonlinear optical properties of organic dyes after Dissolved in Methanol and Epoxy Resin

Abstract

In this paper, some linear optical properties such as (absorbance and transmittance) of an organic dye (Calcein -W) in Methanol and Epoxy resin with different concentration were studied by using UV/VIS spectrum. Nonlinear optical properties of Calcein –W anesthetized in epoxy resin matrix using different concentrations (5*10−5, 1*10−4, 5*10−4, 1*10−3 mol/l) at ambient temperature were studied by using open and closed aperture of Z-scan technique, with continuous wave from Neodymium-doped Yttrium Garnet (Nd: YAG (CW)) laser beams of 532 nm wavelength as an excitation source. The “nonlinear refractive index” (n2), “nonlinear absorption coefficient” (β) of Calcein –W doped film is experimentally determined.
