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.
我们提出了一种窄线宽、线偏振掺钕光纤激光器，它将点式布拉格光栅嵌入到单偏振全固态光子带隙光纤的纤芯中。布拉格光栅是在光纤的单偏振波长带内写入的，因此布拉格反射是偏振的。这种全光纤激光器产生了 7.2 W 的线偏振输出，其 25 pm FWHM 和 19.6 dB 的偏振消光比。
