Our work is studying the optical nonlinearity properties of Chlorophyll-a doped epoxy resin polymer with TiO2 nanoparticle effect. Using EZ-scan technique with continuous wave Nd: Chlorophyll YAG laser operating at (532) nm wavelength as an excitation source. The samples exhibit absorption nonlinearities which due to saturable absorption (SA) process. The nonlinear refractive index n2 is a positive sign, indicates self-focusing optical nonlinearity process. The nonlinear refractive index n2, and the nonlinear absorption coefficient B are found to be of the order of 10-11 cm2/W and 10-1 cm/W respectively. The Tio2 nanoparticle concentration enhancing the nonlinear optical properties of samples.
