| Abstract: | We study a triangular arrangement of two flat mirrors and a grating mirror for coupling a (-1{mathrm{st}}) diffracted order light beam into a traveling-wave intra-cavity light recirculation and out-of-cavity output, combining the (0,{mathrm{th}}) and the repeatedly diffracted secondary (+1{mathrm{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. |
