Abstract

This work reports to the study of third-order nonlinear optical (NLO) susceptibility (χ3) and second-order hyperpolarizability (γ) of a natural dye obtained from chrysanthemum petals. The FT-IR method was utilized to identify the functional groups present in the natural dye. The GC-Mass spectrum was used to find the elemental composition of the pigment. The experiment was carried out using a Z-scan apparatus with a continuous-wave (CW) laser operating at 405 nm wavelength. The closed aperture (CA) and open aperture (OA), were used to measure the natural dye's nonlinear index of refraction (n2) and nonlinear coefficient of absorption (β). The values of n2 and β showcased distinct self-defocusing and reverse saturable absorption (RSA) characteristics of the natural dye. The refractive index and absorption coefficient of the dye were determined to be 4.29 x 10–7 cm2/W and 2.01 x 10–2 cm/W, respectively. The third-order NLO susceptibility of the dye was measured to be 1.41 x 10-6 esu, while its second-order hyperpolarizability was calculated to be 1.02 x 10-30 esu. The study concluded that the natural dye extracted from chrysanthemum petals could be utilized as a suitable NLO material with potential applications in photonics and optoelectronics..
