We have performed a careful experimental study of a high-Q rhodamine 6G ring dye laser and have measured bichromatic emission with wavelength spacings as large as 80 angstroms when the laser operated bidirectionally. The bichromatic emission vanished at all excitations when the laser was forced into unidirectional operation. The experiments show that no discontinuities occur in the intracavity power as a function of excitation and that the intracavity fields which are completely consistent with the measured thresholds are not capable of producing Rabi splittings larger than a few angstroms. We have been able to quantitatively fit the threshold and wavelengths of the bichromatic emission using a distributed feedback analysis with counter-propagating ring modes driving the susceptibility grating.
