The finite-order matrix analysis of choosing property for transverse modes of the Gauss reflective two-dimension resonator with plane and concave spherical reflectors

In this paper,by means of self reproducing theory,the diffraction integral equation of two dimension resonator has been transformed to the finite order matrix equation,and choosing property for transverse modes of the Gauss reflective two dimension resonator with plane and concave spherical reflectors has been numerically analysed,the conclusion is given that the Gauss reflective two dimension resonator with plane and concave spherical reflectors has good choosing capability for transverse modes,which can be applied in high power lasers to acquire good quality of lights for laser treatment on material surface.
