“…This scheme generated an SC source with a The transmission loss between 2 μm and 2.8 μm was less than 2 dB/m, much lower than that of silicon fiber. To further broaden the bandwidth, 30.1-W high-power SC source might be used as the pump source of soft glass fibers 41 . Through the introduction of SC generation in the previous several types of optical fibers, it can be found that SC has developed rapidly in recent years, and SC with different spectral widths, different flatness, and different output powers are emerging in an endless stream.…”

Supercontinuum (SC) generation has attracted a significant scientific interest in the past decades due to its promising applications covering the fields of metrology, spectroscopy, defense, as well as medical treatments. To date, researchers are devoted to improving the spectral width and flatness of SC generation by using specialty optical fibers. The flatness of the spectrum is of importance because it can improve the accuracy of measurement in practical applications. This paper summarizes the theory of SC, the state of the art of flat SC generation using optical fiber including photonic crystal fibers, soft glass fibers as well as germania-doped fibers, and suggests the future research direction of flat SC light source.

“…Mode-locked thulium-doped fiber lasers (TDFLs), which operate in the 2 µm spectral region with pulse duration ranging from nanoseconds to femtoseconds, have attracted a lot of interest due to their applications in mid-infrared supercontinuum generation, remote sensing, laser processing, medicine and free-space communication [1][2][3][4][5][6][7][8][9][10] . In the 2 µm regime, research efforts associated with mode-locked fiber lasers so far have mainly aimed at ultra-short pulse (∼fs or ∼ps pulse) generation.…”

We report on mode-locked thulium-doped fiber lasers with high-energy nanosecond pulses, relying on the transmission in a semiconductor saturable absorber (SESA) and a carbon nanotube (CNTs-PVA) film separately. A section of an SMF–MMF–SMF structure multimode interferometer with a transmission peak wavelength of ∼2003 nm was used as a wavelength selector to fix the laser wavelength. When the SESA acted as a saturable absorber (SA), the mode-locked fiber laser had a maximum output power of ∼461 mW with a pulse energy of ∼0.14 μJ and a pulse duration of ∼9.14 ns. In a CNT-film-based mode-locked fiber laser, stable mode-locked pulses with the maximum output power of ∼46 mW, pulse energy of ∼26.8 nJ and pulse duration of ∼9.3 ns were obtained. To the best of our knowledge, our experiments demonstrated the first 2 μm region ‘real’ SA-based dissipative soliton resonance with the highest mode-locked pulse energy from a ‘real’ SA-based all-fiberized resonator.

“…The germania fiber had a core diameter of 3.5 µm. In order to further scale the output power, Yin et al used a 8 µm core fiber, however this resulted into lower non-linearity and required an input power of 40 W from thulium doped fiber amplifier to reach 3000 nm [4]. This resulted into a system not suitable for many applications where a low average power source between 2 to 3 µm is required to avoid the damage to samples such as imaging and monitoring etc.…”
