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. View article
