我们提出了一种窄线宽，线偏振掺钕光纤激光器，它采用了一个逐点的布拉格光栅刻到一个单一的偏振全固态光子带隙光纤的核心。布拉格光栅被写入光纤的单偏振波长带内;因此，布拉格反射被偏振。该全光纤激光器产生了7.2 W的线偏振输出，具有25 pm的FWHM和19.6 dB的偏振消光比。
We present a narrow-linewidth, linearly polarized neodymium-doped fiber laser that incorporates a point-by-point Bragg grating inscribed into the core of a single-polarization all-solid photonic bandgap fiber. The Bragg grating was written within a single-polarization wavelength band of the fiber; thus, the Bragg reflection was polarized. This all-fiber laser produced 7.2 W, linearly polarized output with 25 pm FWHM and 19.6 dB polarization extinction ratio.
