In this study, the absorption and fluorescence spectra of the dissolved Acridine solution were studied in ethanol and different concentrations. The optical properties (absorption coefficient, linear refraction) and spectral characteristics (Fluorescence time and quantitative fluoridation efficiency) were calculated. It is observed that increasing the concentration increases the absorbance values and decreases the permeability values, thus increasing the values of the absorption coefficient and the refractive index. Also, the values of the fluorine intensity increase. The peak of the emission spectrum is transferred to the longer wavelengths.
The absorption and fluorine spectra of dissolved fluorescein solution in ethanol and different concentrations were studied. The optical properties(absorbance, permeability, linear absorption, and refractive index, as well as time and fluoridation)were calculated. The results showed that a decrease in concentration leads to a decrease in absorption values and an increase in permeability values. This results in a decrease in the values of the absorption coefficient and refractive index. This is in accordance with Lambert's law. Also, the values of the fluorine are lower. The top of the emission spectrum is transferred to the longer wavelengths. The temporal age of fluoride decreases and the quantitative output increases, thus using this dye as an effective laser medium in liquid state lasers. The infrared spectroscopy of the dye was also studied using the (Gaussian 9) program.
In this work, linear optical characteristics of Azure B organic laser dye doped with PMMA polymer dissolved in DMF solvent at concentration (1×10-3 M) were studied. This research includes presenting the results and discussing the absorption spectra and linear optical properties (transmission, linear absorption and refraction coefficient), by studying the effect of adding polymer (PMMA) with different ratios on this pure dye. The result showed that possibility of using this dye in liquid state laser.
