Paper Abstract

A general method to analyse an optical resonator is based on the equivalent resonator theory namely the equivalent confocal system theory, but it can not accurately calculate the field distributions ofthe steady-state modes. In this paper, according to the self-reproducing theory and the angular spectra theory for diffraction, the seven-folded stable resonator with circular diaphragms is numerically simulated, and by FFT (Fast Fourier Transform) laser mode-fields in the folded resonator are spatially traced to obtain the stable laser fields. The computed results indicate that the seven-folded resonator with circular diaphragms can easily obtain the fundamental mode, so it can output laser beams of good quality.
