Abstract
The aim of this work is a comparative study of stochastic laser generation in highly scattering random inhomogeneous media using three dyes as examples: rhodamine 6J, 4-dicyanomethylene-2-methyl-6-[4-(di-methylamino)-styryl]-4H-pyran DCM, and pyridine. The analysis of the obtained experimental data shows that the width of the spectral line tends to a minimum value as the pump pulse energy increases. The transition to the limit state of the spectral quality of the fluorescence response of randomly inhomogeneous media with increasing laser pumping level is observed.
