  • Linearly-polarized, single-frequency fiber lasers
    Patent number: 6167066
    Abstract: Linearly-polarized, single-frequency fiber lasers are realized with optical fibers that have first and second refractive indices in a first fiber grating and third and fourth refractive indices in a second fiber grating. The first and third refractive indices are arranged along a first transverse fiber axis and the second and fourth refractive indices are arranged along a second transverse fiber axis. The grating periods and the first and third refractive indices are selected to generate spectrally-aligned signal reflectances along the first transverse axis and the grating periods and the second and fourth refractive indices are selected to generate spectrally-spaced signal reflectances along the second transverse axis. Thus, a fiber resonator is formed only along the first transverse axis and the fiber laser's output signal is linearly polarized.
