TL;DR: In this article, the properties of image-rotating cavities with 90° image rotation were reviewed and a method for designing them was presented. And the laboratory performance of one promising design was characterized, demonstrating its ability to produce high quality beams with good efficiency.
Abstract: According to numerical models of nanosecond optical parametric oscillators, cavities with 90° image rotation can produce high-quality beams even if the Fresnel number of the cavity is large. We review the properties of such image-rotating cavities and present a method for designing them. The laboratory performance of one promising design is characterized, demonstrating its ability to produce high-quality beams with good efficiency.

TL;DR: The signal beam was more symmetric than that from comparable cavities without image rotation, and it had low values of the beam quality factor, M(2) .
Abstract: 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.

12 Aug 2002TL;DR: In this article, a nonplanar optical parametric amplification (OPAM) system was proposed, where the optical plane formed by two of the mirrors is orthogonal to the optical planes formed by the other two mirrors and with the ratio of lengths of the laser beam paths approximately constant regardless of the scale of the device.
Abstract: A device for optical parametric amplification utilizing four mirrors oriented in a nonplanar configuration where the optical plane formed by two of the mirrors is orthogonal to the optical plane formed by the other two mirrors and with the ratio of lengths of the laser beam paths approximately constant regardless of the scale of the device. With a cavity length of less than approximately 110 mm, a conversion efficiency of greater than 45% can be achieved.

TL;DR: In this paper, a KTiOPO/sub 4/ crystal collinear phase matching optical parametric oscillator (OPO) was designed and built to rotate the image of the resonated wave by 90/spl deg/ on each pass of the cavity.
Abstract: Summary from only given. We designed and built a KTiOPO/sub 4/ crystal collinear phase matching optical parametric oscillator (OPO) that rotates the image of the resonated wave by 90/spl deg/ on each pass of the cavity. Our goal is to verify the predictions of high beam quality from such an OPO even for high pulse energy and large Fresnel number.
