The development of the vector polarized beam presents a new requirement for the mode calculation of the polarization-sensitive resonator.Derived from Fox-Li iterative method and Jones vector theory,a vector Fox-Li iterative method for polarization-sensitive resonator is presented,which can calculates the vector polarization mode in the polarization-sensitive resonator,including the azimuthally polarized TE01* mode and the radially polarized TM01* mode.The vector polarization modes of a spherical polarization-sensitive resonator are obtained by Matlab numerical calculation with this method.The result is coincident with the theory.Then,the 2.17 kW azimuthally polarized beam is obtained based on a fast axial flow(FAF)CO2laser platform using the combined axicon as the rear mirror of the resonator.And it is consistent with the simulated results with vector Fox-Li iterative method,which experimentally corroborates the validity and accuracy of the vector Fox-Li iterative method.The vector Fox-Li iterative method is of great significance for the analysis and design of polarization-sensitive resonator.
