By using the fast-Fourier-transform method and by solving the rate equations, we derived a model of a generalized self-filtering unstable resonator of CO2 lasers with transverse flow. Near- and far-field distributions of various configurations are calculated. The focal length of one mirror is shown as an important parameter to match the resonator with special requirements of application. The theoretical results are in good agreement with experimental data.
