    "abstract": "We present a theoretical model for the spatial mode dynamics of an optical\nparametric oscillator under injection of orbital angular momentum. This process\nis then interpreted in terms of an interesting picture based on a Poincare\nrepresentation of first order spatial modes. The spatial properties of the\ndown-converted fields can be easily understood from their symmetries in this\ngeometric representation. By considering the adiabatic mode conversion of the\ninjected signal, we also predict the occurrence of a geometric phase\nconjugation in the down-converted beams. An experimental setup to measure this\neffect is proposed.",
