The beam quality of the idler output of a 1064 nm pumped OPO based on CdSiP2 is compared for linear and Rotated Image Singly-Resonant Twisted RectAngle (RISTRA) cavities. For similar mirrors and cavity round trip times the RISTRA cavity yielded 64 μJ of idler energy (6.4 mW of average power at 100 Hz) compared to 34 μJ with the linear cavity, at a pump level of 21.5 mJ, roughly two times above threshold. The RISTRA cavity generated a somewhat smoother idler beam spatial profile (characterized by moving a knife-edge) and the intensity in the focus of a 10-cm lens was about 50% higher.
