“…Here, the peak power reached 200 kW level. The simple and compact Tm-doped fiber MOPA generating Raman solitons tunable between 2-2.2 μm with average power up to 3W, pulses as short as 130 fs, and energy up to 38 nJ was demonstrated [21], which is the highest reported pulse energy generation directly from the tunable all-fiber system.…”

, Journal of Lightwave Technology Abstract -We report the high-energy flat-top supercontinuum covering the mid-infrared wavelength range of 1.9-2.5 μm as well as electronically tunable femtosecond pulses between 1.98-2.22 μm directly from the thulium-doped fiber laser amplifier. Comparison of experimental results with numerical simulations confirms that both sources employ the same nonlinear optical mechanism -Raman soliton frequency shift occurring inside the Tm-fiber amplifier.To illustrate that, we investigate two versions of the compact diode-pumped SESAM mode-locked femtosecond thulium-doped all-silica-fiber-based laser system providing either broadband supercontinuum or tunable Raman soliton output, depending on the parameters of the system. The first system operates in the Raman soliton regime providing femtosecond pulses tunable between 1.98-2.22 μm. Wide and continuous spectral tunability over 240 nm was realized by changing only the amplifier pump diode current. The second system generates high-energy supercontinuum with the superior spectral flatness of better than 1 dB covering the wavelength range of 1.9-2.5 μm, with the total output energy as high as 0.284 μJ, the average power of 2.1 W at 7.5 MHz repetition rate. We simulate the amplifier operation in the Raman soliton self-frequency shift regime and discuss the role of induced Raman scattering in supercontinuum formation inside the fiber amplifier. We compare this system with a more traditional 1.85-2.53 μm supercontinuum source in the external highly-nonlinear commercial chalcogenide fiber using the Raman soliton MOPA as an excitation source.The reported systems 1 can be readily applied to a number of industrial applications in the mid-IR, including sensing, stand-off detection, medical surgery and fine material processing.

“…The wide spectral tunability can be obtained by the Raman soliton amplification externally or directly in the amplifier [3,21]. In particular, tunability over 140 nm range was demonstrated after amplification of Raman soliton in external Tm-doped fiber (TDF) [22], 108 fs pulses with energy of 31 nJ and average power of 3.1 W were obtained.…”

“…Increasing the amplifier output power up to ~100 mW was accompanied by spectrum broadening, figure 3(a). Simultaneously, the spectrum became asymmetric with a noticeable increase of the low-energy side due to the Raman amplification, ending up in formation of a Raman soliton similar to [14].…”

We report a simple method of generating a spectrally flat and high average power spectral density (up to 14 mW/nm) optical supercontinuum in the 1.95-2.5 μm range covering a transparency window of the atmosphere. The supercontinuum was generated from the Tm-doped all-fiber MOPA lasers. The average output power of the picosecond linearcavity SESAM mode-locked seed lasers operating at 46 and 77 MHz was as low as 6.7 and 2.6 mW, respectively. The corresponding one-stage silica-based fiber amplifier generated a supercontinuum with 5.06 and 6.83 W average power, 550 and 500 nm bandwidths at −10 dB level, and 5 and 8 dB spectral flatness, respectively.
