Paper Abstract

We describe the generation and amplification of femtosecond pulses at 2-μm wavelength in thulium doped fiber. The mode-locked oscillator is a ring cavity based on single-mode Tm:fiber producing stable soliton pulses at 70 MHz repetition rate with 40 pJ pulse energy, centered at ~1.97 μm wavelength with ~8 nm (FWHM) spectral width. These pulses seed a Tm:fiber based Raman amplifier, which increases the energy up to 9 nJ. The spectrum is broadened up to 40 nm (FWHM) and the center wavelength can be shifted from ~1.97- 2.15 μm. The Raman solitons are inherently time-bandwidth limited with pulse durations <150 fs.
