Abstract
A narrow-linewidth fibre laser operating at 1178nm that employs a double-clad Yb3+-doped hybrid microstructured fibre, is demonstrated. The fibre suppresses amplified spontaneous emission by the photonic bandgap effect, and parasitic lasing at shorter wavelength range (1030-1100nm) was prevented. A narrow-linewidth (<0.05nm), CW output of 0.5W at 1178nm with a slope efficiency of 14, was measured.
