This experimental work is about the non-linear optical properties of two organic materials based on Z-scan method. The laser that used in this experimental method is a continuous wave diode pump laser at 532 nm wavelength and experiments were performed at one intensity. The depicted curves and the peak-valley arrangements show the non-linear refractive index for both matter is negative which indicates the self-defocusing effect. The analysis of the depicted curves for both materials shows that the sample of saffron has a better non-linearity than the sample of Hibiscus Sabdariffa and also has higher two-photon absorption threshold.
