• We examine how much the oscillation characteristics of DC-excited gas lasers are influenced by the flow of a laser medium. Expressions for the gain and phase constants of a laser medium, the output power, and the spot size of a laser beam are derived as functions of the frequency and the ratio of the drift velocity of the active atoms or molecules to the velocity due to thermal motion. Although the gain and phase constants and the output power are still symmetric (or antisymmetric) with respect to the center frequency (even with a gas flow), the derived expressions indicate some quantitative changes in those oscillation parameters with a gas flow. Xe, He-Ne, and CO_2 lasers are treated as numerical examples.
