Determnation Of Optical Parameters of Dye Lasers Coumarin500 and Rhodamine 6G in Different Solvents

Abstract

The primary goal of this research is to obtain laser radiation from two dyes, (Coumarin500 & Rhodamine 6G), study the resulted laser properties and study the effect of different solvents on the laser output. In this work, two dyes (Coumarin500 & Rhodamine 6G) were dissolved each separately in three different solvents (acetone, methanol and ethanol) with two concentration levels values (1.4 & 1.6 g/l). Optical properties of dyes solvents and solutions (transmission, absorption and emission) were successfully determined. These solutions optically pumped by nitrogen laser of wavelengths (337nm) using Hansch cavity configuration to produce laser. In the case of the first Dye, (Coumarin 500) no laser radiation obtained for all solutions (acetone, methanol and ethanol) in all concentrations, While trials with the second dye (Rhodamine 6G), we produced laser successfully when the dye dissolved in all solvents used in this work with the concentration 1.6g/l.
