Abstract

We present an analytic method for obtaining phase-matching conditions for general three-wave mixing in biaxial crystals. The method is based on a rarely quoted closed-form solution to the Fresnel equation. Additionally, we show how the method can be used to obtain acceptance angles for both critical and noncritical phase matching and apply the derived formulas to two examples.
