Efficient, narrow-linewidth Tm-doped fiber lasers operating in the 1.7 μm wavelength regime
are of significant importance for a wide range of applications. To achieve high-power 1.7-μm …

We investigate the operation of holmium-doped fibre amplifiers (HDFAs) in the 2.1 µm
spectral region. For the first time we demonstrate a diode-pumped HDFA. This amplifier …

We proposed a novel photonic crystal fiber composed of a double-cladding square lattice
