英文摘要：

A photosensitive polarization-maintaining erbium-doped fiber was fabricated experimentally and a high efficiency resonance cavity was set up by writing three fiber Bragg gratings on this fiber using UV laser. The mono-wavelength laser with mean output power of 9.20 dBm and mean wavelength of 1554.554 nm was produced by pumping at a power of 23.617 dBm and wavelength of 976 nm. The fluctuations of output power and wavelength were less then ± 0.05 dB and ± 0.0015 nm for a test time of 800 min, respectively, at room temperature.
