Improving the Linear and Nonlinear Optical Properties of Two Laser Dyes, Pure Rhodamine B and Methyl Violet by Mixing them

Abstract The present research include studying the structural ,linear and nonlinear optical properties for two organic laser dyes: Rhodamine B (RB) and Methyl violet (10B) The linear optical properties for all prepared samples have been studied, a study of UV-VIS spectra for different concentrations for each dye dissolved in absolute ethanol solvent, then study of absorption and transmission spectra for all samples. The spectral optical properties of all the prepared samples have been studied using fluorescence spectroscopy. The results showed when the concentrations increased the absorbance also increased for the same wavelength. The opposite relationship was observed for transmittance.
