摘要： A ring laser gyroscope includes active cavity containing gain medium, first reflective surfaces coupled to active cavity, medium exciter to excite gain medium, second reflective surfaces coupled to first passive cavity, and third reflective surfaces coupled to second passive cavity. Excited gain medium induces first and second laser fields within active cavity.

Second plurality of reflective surfaces includes first, fourth, and fifth reflective surfaces that reflect light within first passive cavity. Third plurality of reflective surfaces includes fourth, sixth, and seventh reflective surfaces that reflect light within second passive cavity. First and fourth reflective surfaces are partially transmissive such that they both transmit and reflect light. Second or third cavities induce frequency dependent phase shift on light traveling through ring laser gyroscope causing anomalous dispersion of first and second laser fields passing through gain medium.
