“…Through filtering, one can obtain an optical spectrum similar to that of fiber oscillators while eliminating the self-mode locking characteristic [19,20]. In the past decade, extensive efforts have been devoted to the high power SFSs with narrowband output spectra [21][22][23][24]. Moreover, based on the master oscillator power amplifier (MOPA) configuration, the output power of narrowband SFS has been scaled to several kilowatts [23,24].…”

Superfluorescent fiber source (SFS) with tunable optical spectrum has shown great application potential in sensing, imaging and spectral combination. Here we demonstrate for the first time, a 2-kilowatt-level wavelength and linewidth tunable SFS.Based on a flexible filtered SFS seed and three stages of fiber amplifiers, the output power can be scaled from milliwatt level to about 2 kW, with a wavelength tuning range of 1068-1092 nm and a linewidth tuning range of 2.5-9.7 nm. Moreover, a numerical simulation is conducted based on the generalized nonlinear Schrödinger equation, and the results reveal that the wavelength tuning range is limited by the decrease of seed power and the growth of amplified spontaneous emission, while the linewidth tuning range is determined by the gain competition and nonlinear Kerr effects. The developed wavelength and linewidth tunable SFS may be applied to scientific research and industrial processing.

“…also puts forward a demand for high-power short-wavelength and long-wavelength lasers [3], [4]. There has been reports on high-power short-wavelength fiber lasers in the last decade [5], [6], [7], [8], [9]. In 2016, Naderi et al reported a fiber laser based on phase-modulated single-frequency laser [5].…”

Tapered Yb-doped fiber (T-YDF) can balance the suppression of transverse mode instability (TMI) and stimulated Raman scattering (SRS) in high power fiber lasers. In this work, we have constructed an all-fiberized master oscillator power amplifier emitting at the central wavelength of 1050 nm based on a T-YDF and investigated the laser performance in respective co-pumped and counter-pumped configurations. The results show that the T-YDF can effectively mitigate SRS effect in short-wavelength fiber lasers.A nearly single mode beam quality (M2∼1.20) is obtained at output power of 3 kW-level. In particular, the SRS suppression ratio in the co-pump and counter-pump scheme is about ∼33.2 dB at ∼3039 W and ∼46.6 dB at ∼2818 W, respectively. By further optimizing the structure of the tapered active fiber, it is promising to further improve the output power and beam quality in short-wavelength fiber lasers.
