    摘要： A single-frequency Brillouin fiber ring laser with extremely narrow linewidth comprises a single-frequency narrow-linewidth rapid-tunable pump laser, a temperature-controlled acoustically-damped package for Brillouin fiber ring laser cavity, and an auto-tracking feedback electronic loop with novel configuration for active stabilization. The Pound-Drever-Hall frequency-locking technique is employed to keep pump laser frequency in resonance with one of the Brillouin fiber ring cavity modes. Instead of changing cavity length of Brillouin fiber ring laser, the pump laser frequency is rapidly tuned in the auto-tracking feedback electronic loop. This enables extremely narrow linewidth radiation emitted from a Brillouin fiber ring laser without stretching the fiber ring. Dual-wavelength actively stabilized Brillouin fiber ring laser may be generated from a single ring cavity by polarization-combining or wavelength-combining two pump laser beams and using two independent feedback loops to the two operation wavelengths.

    摘要： An all-fiber Faraday rotator including a plurality of optical fibers doped, at unusually high concentrations of at least several tens of percent, with rare-earth oxides, an all-optical-fiber optical isolator employing a polarization-maintaining fiber-optic splitter, and a method of optically-isolating a laser source from unwanted feedback with such an optical isolator. In a case where the doping concentration exceeds 55 weight-%, the length of the Faraday rotator achieving a 45-degree rotation of the polarization vector of light guided by an optical fiber does not exceed approximately 10 cm.

    摘要： A distributed fiber sensor based on spontaneous Brillouin scattering uses a single-frequency fiber laser as a source and a cw Brillouin fiber ring laser as an OLO to optically shift the frequency of the OLO to set the Brillouin/OLO beat frequency within the bandwidth of a conventional heterodyne receiver. The distributed fiber sensor is capable of real-time measurement of both temperature and strain.
