The RLG includes a primary resonator, a secondary resonator, and an optical source to provide a pump field. The pump field in the primary resonator stimulates an optical gain curve at a first stokes wave frequency. A first order SBS field stimulates a second optical gain curve at a second stokes wave frequency. The second order SBS gain gives rise to a frequency-shifted field propagating in the first direction. The fraction of the pump field that couples out of the primary resonator, through the secondary resonator, and out of the secondary resonator is larger than the fraction of: the first order SBS field that couples out of the primary resonator, through the secondary resonator, and out of the secondary resonator; and a second order SBS field that couples out of the primary resonator, through the secondary resonator, and out of the secondary resonator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stimulated Brillouin scattering (SBS) gyro with coupled resonator for frequency-dependent output coupling","description":"A ring laser gyroscope (RLG) is provided.
