Mid-IR Supercontinuum Generation Pumped by Femtosecond Thulium Doped Fiber Amplifier

We present a mid-infrared supercontinuum generation pumped by a femtosecond thulium doped fiber laser with an octave-spanning spectrum from 1.1 to 3.7 μm. The spectral flatness of 10 dB over a 1390 nm range has been obtained from 1940 - 3330 nm.
