摘要： A ring laser gyroscope that includes a cavity containing a gain medium, a first plurality of reflective surfaces coupled to the cavity, a medium exciter operable to excite the gain medium, and a saturation beam source operable to emit a saturation beam. The first plurality of reflective surfaces includes a first reflective surface, a second reflective surface, and a third reflective surface. The first, second, and third reflective surfaces are positioned to reflect light along a path defined in the cavity between the plurality of reflective surfaces. The excited gain medium induces first and second laser fields within the cavity. The emitted saturation beam intersects with the first and second laser fields at a first interaction region of the cavity. The saturation beam interacts with the gain medium to reduce the gain of the first and second laser fields at a first range of frequencies.

- une source cohérente (4) émettant une onde cohérente à une longueur d'onde sensiblement égale à celle de l'onde signal et dont la direction de propagation est inclinée par rapport à la direction de propagation des ondes optiques issues des fibres amplificatrices ;
- des moyens pour faire interférer l'onde cohérente et les ondes optiques issues des fibres amplificatrices et générant un interférogramme constitué d'un réseau de franges ;
- des moyens de détection de l'interférogramme (7), le positionnement relatif des franges transcrivant une loi de phase entre fibres;
- un modulateur spatial de phase (2) ;
- des moyens d'affichage et de traitement (6) de la loi de phase détectée sur le modulateur spatial, ledit modulateur spatial étant positionné de manière à pouvoir être lu par l'onde signal et ainsi générer une onde signal modulée en phase de manière sélective au niveau de chacune des fibres compensant les déphasages induits par lesdites fibres.

摘要： An optical system (30, 40, 50, 60, 70, 80, 90, 100, 130, 140, 150, 160, 170, 230, 3000, 4000, 5000, 6000, and 7000) has a transmission filter device (34, 44, 54, 64, 74, 84, 94, 104, 134, 144, 154, 164, 174, 234, 3500, 4500, 5400, 6500, 7500), a feedback mechanism (38, 48, 58, 68, 78, 88a-88d, 98a-98b, 105, 135, 148, 158, 168a-168b, 178, 238, 3800, 4800, 5800, 6800, 7800), and one or more radiation sources (32, 42a-42b, 52a-52d, 62a-62b, 72a-72d, 82a-82d, 92a-92d, 102a-102d, 132a-132d, 142a-142b, 152a-152b, 162a-162b, 172a-172d, 232a-232d, 3200a-3200n, 4200a-4200n, 5200, 6200a-6200n, 7200a-7200n). Each radiation source generates an output signal with a predetermined wavelength band and polarization and is coupled to a separate input port of the transmission filter device. The transmission filter device, which is responsive to output signal from each radiation source, generates an output signal from at least one output port thereof. The feedback mechanism is coupled to at least one output port of the transmission filter device for providing a feedback signal that is directed back through the transmission filter device device to each of the radiation sources for stabilizing each of the radiation sources. The apparatus is polarization maintaining wherein the one or more radiation sources, the transmission filter device, and the feedback mechanism are interconnected such that principle axes of polarization thereof are substantially aligned.
