“…[14] It is to be noted that, although several high-power Raman fiber lasers with fixed wavelengths have been reported with hundred-watt level output power, [15][16][17][18][19] the output power of tunable Raman fiber lasers is still rather low, i.e., no more than the 10 W level. Besides high output power, linearly polarized operation is also an important demand in many applications owing to high efficiency, [20,21] such as harmonic generation, [22,23] parametric conversion, [24,25] coherent detection, coherent beam combination, [26,27] spectral beam combination, [28,29] and supercontinuum generation. [30,31] Nevertheless, to the best of our knowledge, there have been no reports on high power linearly-polarized tunable Raman fiber lasers yet.…”

“…However, for SBC by VBG, combining five channels has only possessed a 1 nm spectral band [7], and for interference filter combining, the combined spectral range covers around 1030 [9] or 1050 nm [10]. Even for diffraction grating SBC, experimental implementation of a spectral band has possessed less than 24 nm [11,[18][19][20], deficient in useful Yb-gain bandwidth covers more than 100 nm.…”

“…For example, YDFLs at wavelength ranges of 1010-1020 nm with narrow bandwidths can not only be frequency quadrupled to 25× nm for laser-induced fluorescence, optical refrigeration, semiconductor inspection and atomic trapping applications [3][4][5][6][7] but can also be used for tandem-pumping high-power C-band (1.06-1.12 µm) YDFLs, due to their smaller quantum defect which gives higher conversion efficiency and lower thermal load [8,9] . Moreover, as an outstanding pathway for achieving scalable high-power lasers with good beam quality, spectral beam combining (SBC) combines multiple lasers into a single beam for maximum output power [10][11][12][13][14][15][16][17] . To date, the most common wavelength range for SBC is from 1050 to 1080 nm.…”
