Abstract
The non-linear optical characteristics of organic laser dyes (Acriflavine,Orcein, and Azur-B) dissolved in Ethanol solvent with concentration (10−5M) were investigated in this study. The UV-VIS spectrophotometer measures the spectra' linear optical characteristics. It was determined the nonlinear optical characteristics by using the Z-Scan method, which represents a very sensitive approach for obtaining two essential optical phenomena: nonlinear refractive index and nonlinear absorption coefficient, in two different situations (close aperture) and (open aperture). The results indicate (Acriflavine,Orcein, and Azur-B) is a promising material to be used in photonic and nonlinear optical devices.An optical power limiter uses this promising medium for a range of optoelectronic applications.
