Abstract :
Based on diffractive theory and experimental work, a binary optical resonator (BOR) was developed according to phase-conjugate principle. Replacing the sphere mirror of a high power CO/sub 2/ laser simi-confocal resonator (SCR) with a 16-levels binary optical mirror (BOM), having square aperture, a square-cross-section 10/sup th/ order super-Gaussian beam was specified as the eigenmode of the new resonator.
