A general method of approach to nonlinear optical problems involving traveling-wave beams produced by the spherical Febry-Perot-type open resonator has been developed. It is shown how coupled-mode equations can be obtained for the nonlinear interaction of these modes from Maxwell's equations describing the wave propagation in the nonlinear medium. The coupling coefficients for second-harmonic generation are calculated as an example of the use of the method. From these general results, effects arising from position and strength of focusing may be obtained.
