We performed laboratory and numerical modeling studies of an optical parametric oscillator with 90° intracavity image rotation. We found that the signal beam was more symmetric than that from comparable cavities without image rotation, and it had low values of the beam quality factor, M2 . Oscillator performance agreed well with our numerical model.
