3-(3,4-dimethoxyphenyl)-1-(2,5-dimethylfuran-3-yl)prop-2-en-1-one (DDFP), is prepared by the equimolar ratio of 1-(2,5-dimethylfuran)ethan-1-one and 3,4, dimethoxy benzaldehyde under ultrasonic irradiation. Structure of DDFP was established by the FT-IR, 1H and 13C-NMR spectroscopic methods and elemental analysis. The nonlinear optical properties of this dye using the z-scan technique with a cw argon ion laser at 514.5 nm are studied. Both the closed and open aperture z-scan data is used to estimate the nonlinear refractive index n2 and the nonlinear absorption coefficient β respectively. The measurements are carried out at five concentrations as well as at five laser powers. The values obtained are relatively very high and vary linearly with concentration. The studies on optical limiting behavior of this dye are also reported here. [ABSTRACT FROM AUTHOR] |
