摘要

Abstract: A laser beam with uniform intensity and plain phase is advantageous for many applications. Based on diffractive theory, a binary optical resonator was developed according to phase-conjugate principle in this paper. Replacing the sphere mirror of a semiconfocal resonator with a 16 levels binary optical mirror, having square aperture, a square- cross-section 10th order super-Gaussian bema is designed as the eigenmode of the new resonator. A few different original beam distributions mirror can select the desired beam profile or not. THe resulting square-cross-section 10th order super-Gaussian fundamental mode reproduced itself after some roundtrips in the laser resonator successfully and the other modes were attenuated. !11
