Abstract: The objective of this research endeavour is to analyse the spectrum, linear and nonlinear optical characteristics, and the utilization of condensation (10-5M) doped with polymer and nanomaterials in (Azure-A) organic laser dye. Polymer and nanoparticle compounds have the potential to develop various features of organic dyes, which has practical uses. The spectral optical characteristics of every prepared sample were investigated by means of a spectrophotometer. The Z-Scan method was employed to measure the nonlinearity in two sections (open and close aperture) in order to obtain the nonlinear absorption factor (β) and refract tile index (n2). The studies were conducted using a solid-state laser with a wavelength of (457 nm). The study found that as the nonlinear refractive index rose, the absorption coefficient decreased, and as (n2) increased, (β) increased in all samples. It was discovered that the doped samples containing the polymer had enhanced nonlinear properties, and that the nonlinear refractive index of every sample rose when the laser's power was raised. In contrast, when sample power rises, the nonlinear absorption coefficient decreases for all samples.
