ABSTRACT: Nowadays the dye
lasers play as an important tool and are used in many applications including
spectroscopy, medicine and dermatology. This research was carried out to study
the possibility of using the beet dyes as a laser gain medium. The fluorescence
quantum yield was determined by the comparative method with rodamine b as an organic dye standard. The value
of the fluorescence quantum yield was found about (0.14) and the fluorescence
quantum yield was developed until reaching about (0.323). The increasing of
fluorescence quantum yield of dye solution as a result of increasing the viscosity
of solvent was observed clearly. The study concluded that the beet dyes are
so sensitive to fluorescence and it is very suitable to be used as a laser gain
medium.
