Abstract
A cavity design for use with a nonlinear medium which may be used as an oscillator using pump energy with frequency (FP) interacting with the nonlinear medium for parametrically generating outputs having a signal frequency (FS) and an idler frequency (FI) which satisfy the relationship FP=FS+FI. The cavity consists of optics and optical elements that minimize the buildup of intracavity intensity at either of the parametrically waves being generated, creating a condition in which the optical cavity is non-resonant for both the signal and idler frequencies.
