Abstract
The method of obtaining wave beams of a uniform intensity profile in the waveguide metal rectangular resonator is described. It is based on the self-imaging properties of multimode rectangular waveguide and using a heterogeneous mirror with the discretely distributed absorbing or scattering sections. The theoretical model and calculation algorithm of characteristics of the low-loss Fourier-mode with uniform intensity distribution at the output mirror of the WQR are developed with application of the eigen modes and the Fourier-optics methods. The conditions of Fourier-mode existence are established by changing the resonator geometry and its heterogeneous mirror parameters.

KEY WORDS: rectangular waveguide resonator, phase-shifting mirror, the Fourier-optics, laser beam shaping
