Abstract : A high efficient narrow linewidth fiber laser  based on fiber Bragg grating Fabry- Perot( FBG F- P) cavity was demonstrted. The spatial hole burning effect was restrained by fiber Faraday rotator( FR) . Two short FBG F- P cavities as narrow bandw idth filters discriminated and selected the laser longitudinal modes efficiently. Stable single frequency 1550nm laser was acquired. Pumped by two 976nm LD, the fiber laer exhib ited a 11 mW threshold. The 73mW output power was obtained upon the maximum 145mW pump power. The optica-l optical  efficciency was 50% and the slope efficiency was 55% . T he 3 dB linewidth of laser was less than 10 kHz, measured by the delayed sel-f heterodyne method with 10 km mono- mode fiber. T he high power narrow linewidth fiber lasr can be used in high resolution fiber sensor system. 1 Introduction As a  fiber laser sensor source, the narrow linewidth fiber laser has the characteristics of interference to the electromagnetic field,...
