Study of the thermal and nonlinear optical properties of alizaringelb R solution

The thermal and nonlinear optical (NLO) properties of alizaringelb R solution are investigated experimentally and numerically. The thermal conductivity, K, of alizaringelb R solution is calculated by constructing a device and found to decrease with the increase in absolute temperature. The change in refractive index, \(\Delta \) $\mathrm{\Delta }$ n, of alizaringleb R solution and its nonlinear index of refraction (NLIR), n₂, are estimated via diffraction patterns (DPs) under irradiation with a 473 nm cw laser beam. As high as 4.73 × 10^–3 and 4.81 × 10^–11 m²/W of \(\Delta \) $\mathrm{\Delta }$ n and n₂ are determined. The collapse of DPs phenomenon through the deformation of the resulted DPs seen to occur. The resulted DPs are numerically calculated via the use of a mathematical model that is solved using the diffraction integral.
