“…At the same time, HiPco tubes are very efficient for Er, Pr, Bi-doped fibre lasers [62,128,129]. Finally, SWNTs grown by the laser ablation method usually have a narrow diameter up to 1.4 nm distribution and can be applied for Er, Tm, Hodoped fibre lasers [56,71,129].…”

“…The diameter of the degradation spot is comparable with the effective mode field diameter of the optical fibre. However, several recent works show the high potential of such SA for high-power operation [71,129]. Polymer nanocomposites allow alignment of SWNTs by their stretching [182] or fabricating with the LangmuirBlodgett technique [212] due to the high anisotropic interaction of SWNTs with light.…”

Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation in fibre laser cavities putting emphasis on stateof-the-art fibre lasers, mode locked using CNT-SA. We discuss new design concepts of high-performance ultrafast operation fibre lasers covering ytterbium (Yb), bismuth (Bi), erbium (Er), thulium (Tm) and holmium (Ho)-doped fibre lasers.

A compact all-in-line graphene-based distributed feedback Bragg-grating fiber laser (GDFB-FL) with narrow linewidth of hundreds kHz is demonstrated and investigated in this study. Performing as an optical saturable absorber, graphene oscillates the initially kHz linewidth DFB-FL, and generates high-quality passively Q-switched pulses. Pumped with a 980 nm continuous-wave laser, the Q-switched GDFB-FL observes ~1 μs pulse durations, with pulse energies up to ~10 nJ and approaching the transform limit. The peak power is ~600 times higher than the original DFB-FL laser. By optimizing the cavity design and the graphene material, it is predicted that fast Q-switched pulses with more than MHz repetition rates and sub-100 ns pulse durations are achievable. Such transform-limited Q-switched GDFB-FLs with narrow linewidth of sub-MHz have long coherence length, good tunability, stability, compactness and robustness, with potential impact in optical coherent communications, metrology and sensing.
