摘要
We have studied the absorption performance of the organic dye Disperse Blue 1 (DB1) in dioxane at different concentrations. Solutions were exposed to high intensities of CW laser radiation with the following wavelengths: 632.8 nm (He-Ne laser), 488, 496, and 514 nm (argon-ion laser). DB1 solutions showed optical limiting at high intensity of 632.8 nm laser radiation, which is very close to DB I maximum absorption. Very dilute solution of the order of similar to 10(-4) M was enough to limit the transmitted power of the incident laser light by more than 90%. However, for other Ar-ion laser wavelengths, concentrations as high as 7.46x10(-4) M were needed for the optical limiting characteristics to be observed.
