Abstract :
We demonstrate a 38 dB gain thulium doped fiber amplifier pumped by 400 mW at 1050 nm that uses a reflective double-pass configuration. The gain enhancement is 16 dB and the maximum noise figure penalty is 2 dB for the double-pass compared to single-pass operation. We also compare the performance of two configurations of double-pass operation, with a mirror and with a circulator as the reflector.
