    "abstract": "We study the effects of higher order transversal modes in a model of a\nsingly-resonant OPO, using both numerical solutions and mode expansions\nincluding up to two radial modes. The numerical and two-mode solutions predict\nlower threshold and higher conversion than the single-mode solution at negative\ndispersion. Relative power in the zero order radial mode ranges from about 88%\nat positive and small negative dispersion to 48% at larger negative dispersion,\nwith most of the higher mode content in the first mode, and less than 2% in\nhigher modes.",
