Abstract: A frequency processing system (1000, 1100, 1200, 1300) for detecting, tuning, or stabilizing light frequency or wavelength in a light beam (1012, 1112, 1212, 1312) produced by a light source (1010, 1110, 1210, 1310). A grating block (1014, 1114, 1214, 1314) receives the light beam (1012, 1112, 1212, 1312) and may produce diffracted beams (1018, 1118, 1218, 1318a-b) and a passed beam (1016, 1116, 1216, 1316). The diffracted beams (1018, 1118, 1218, 1318a-b) are received by respective detectors (1020, 1120, 1220, 1320a-b) which produce measurement signals (1022, 1122, 1322a-b) that are communicated to a processor (1024, 1124, 1224, 1324). The processor (1024, 1124, 1224, 1324) then produces control signals (1026, 1126, 1226, 1326a-b) that are communicated to the light source (1010, 1110, 1210, 1310) where they are usable for detecting, tuning, or stabilizing the light frequency or wavelength.
