We study a triangular arrangement of two flat mirrors and a grating mirror for coupling a - 1 st diffracted order light beam into a traveling-wave intra-cavity light recirculation and out-of-cavity output, combining the 0th and the repeatedly diffracted secondary + 1 st order beams. The thus designed and then optimized grating Fabry-Perot ring cavity demonstrates high output contrast and detection resolution for wavelength, cavity length and incidence angle.
