Abstract: In this paper a theoretical consideration of quasi-steady- state generation of dye lasers (DL) with an isotropic Fabry- Perot-type resonator and coaxial (longitudinal) laser pumping is presented for the regime of saturation in the orientation distribution of excited molecules. Our analysis is carried out for cases of parallel and orthogonal mutual orientation of dipole moments of transitions with absorption and emission in dye molecules. The effect of intensity and polarization state of longitudinal pumping on the degree of linear polarization and output intensity of DL has been clarified. A preference of circular pump polarization occurs in our theory. The comparison of the results obtained with the experimental studies is also performed.!20
