Abstract

Organic laser dyes Rhodamine B (RB) and Aniline Blue (AB) have linear optical properties were determined at different concentrations (2´10-5, 4´10-5, 6´10-5, and 8´10-5,M)at room temperature with an ethanol solvent. The absorbance intensity range shifts toward the longer wavelengths (red shift) with respect to the AB dye, while the absorbance intensity shifts towards the shorter wavelengths (blue shift) with respect to the RB dye. Organic laser dyes have a wavelength range of 520-690 nm. As compared to individual laser dyes, the findings show that a mixture of laser dyes is an efficient optical material. It can be used as a cavity laser resonator.
