This paper reports on the power-dependent nonlinear optical (NLO) attributes for both nonlinear refractive index, n2 and nonlinear absorption coefficient, β of Ponceau BS (PBS) chromophore, a synthetic organic compound that falls under azo family. Single-beam Z-scan technique was utilized for the no...
