Abstract : The resonator comprises a pair of confronting spherical mirrors with birefringent material between them. This structure results in two resonant frequencies within the resonator which must be excited with orthogonally polarized light beams. The input light beam is arranged to excite each of the resonant modes equally, and a beam splitter and a pair of polarizers separate the responses of the resonator at the two resonant modes. One of such responses is subtracted from the other to form the discriminator S-curve. (Author)
