Paper Abstract

We have constructed and tested an imaging unstable ring resonator of Newtonian telescope type with an infinite Fresnel number for Nd:YAG laser oscillator. The wavefronts characteristics is analyzed based on the fringe patterns from Mach-Zehnder interferometer. We observe the approximately uniform intensity profile and wavefront phase over the transverse plane. Fringe analysis by using Fourier transform method shows that the distortion of wavefronts is less than 0.2 λ. In comparison with the wavefront flatness of a standing-wave-type laser output beam, that of the NBUR Nd:YAG laser output beam was enhanced by up to 75 %.
