Based upon the rate equation formalism the problem of the existence of different longitudinal modes within the active cavity of a cw gas-dynamic laser is considered. The flat parallel mirror cavity supplied with a fast transverse flow of the optically active medium is analyzed. The analytical formulas for the total output power and laser efficiency are given as well as for the single-line output and single-line load coefficients (efficiencies). The CO$sub 2$ and/or CO$sub 2$/N$sub 2$/H$sub 2$O(He) molecular mixture is kept in mind as a practical analogue for the optically activated medium under consideration. A numerical example concerning a cw gas-dynamic laser driven by benzene combustion in air is presented.
