We report what is believed to be the first observation of a nonlinear mode in a cylindrical nonlinear Fabry–Perot cavity. The field enhancement from cavity buildup, as well as the large χ(3) optical nonlinearity that is due to resonantly excited 85Rb vapor, allows the nonlinear mode to form at low incident optical powers of less than 1 mW. The mode is observed to occur for both self-focusing and self-defocusing nonlinearity.
