Thulium-doped fiber amplifier for optical communications at 2 µm.
We report the first experimental realization and detailed characterization of thulium doped fiber amplifiers (TDFAs) specifically designed for optical communications providing high gain (>35 dB), noise figure as low as 5 dB, and over 100 nm wide bandwidth around 2 µm. A maximum saturated output power of 1.2 W was achieved with a slope efficiency of 50%. The gain dynamics of the amplifier were a...
متن کاملComparative Studies of the Thulium and Erbium Doped from 1480-1650 nm with Different Host Materials as Optical Fiber Amplifiers
This work describes the comparison of the amplification characteristics (gain) and the Noise figure (NF) of the Thulium and Erbium in three different host materials which the Yttria Alumina-Silica glass, Fluoride and Tellurite fiber glass. The gain using these host materials covers the range 1.45-1.65 μm. Thulium doped fiber amplifier (TDFAs) operated in the region of wavelength (1480-1510 nm) ...

متن کامل50-W 2-μm Nanosecond All-Fiber-Based Thulium-Doped Fiber Amplifier
We report a two-stage 2-μm Tm3+ fiber amplifier seeded by an acousto-optic modulator (AOM) modulated narrowbandwidth pulsed laser. Maximum output average power is over 50 W (slope efficiency of ∼58%) at 50 kHz repetition rate, providing record performance in nanosecond 2-μm all-fiber-based amplifiers. The maximum pulse energy and peak power are ∼1.0 mJ and 10 kW, respectively. The pulse width c...
متن کاملThulium-doped silica-based optical fibers for cladding pumped fiber amplifiers
We present preparation and spectroscopic characterization of the Tm-doped fibers with enhanced 3H4 fluorescence lifetime thanks to codoping with alumina. With the alumina content of 10 mol %, the fluorescence lifetime of 58 s was achieved. Using experimentally obtained fiber characteristics, we used numerical simulations to study and optimize for the first time the thulium-doped fiber amplifie...
