Abstract: | Thulium doped fiber amplifier is a good candidate for S, and S+ band. This paper demonstrated a three pump pumping scheme for thulium doped fiber amplifier with 1050 nm co propagating pump and 1400 nm and 800 nm counter propagating pumps with a total pumping power 600 mW. This configuration yields up to 33 dB gain in 20 nm region from 1460 nm to 1480 nm, with noise figure <4 dB. To the knowledge of authors it is the highest gain achieved by thulium-doped amplifier in a single pass configuration with good power conversion efficiency. |
