Abstract
Line narrowing in the output spectrum of a Nd-doped silica-fiber laser with spectrally flat reflectors is interpreted to indicate a substantial homogeneous contribution to the 1.09-μm fluorescent linewidth. By using a fiber Bragg reflector, frequency-stable operation with 100-GHz bandwidth is obtained, dominated by power broadening and spectral hole burning.Keywords
