“…Secondly, our absorber is not fully bleached and follows the instantaneous intensity. This is also a significant difference from the case reported in [20], in which the absorber relaxation dur ing the pulse emission period was neglected because of a relatively long recovery time [33]. The minimum pulse width achieved in our experiments was 245 ns that was significantly longer than the corresponding result of 20 ns in [20], which we attributed to the longer fiber length and relatively weak pump intensity due to the cladding pumping scheme.…”

We demonstrate a diode pumped passively Q switched Tm doped double cladding silica fiber laser operating at wavelength of 1960 nm using an anti resonant Fabry Perot saturable absorber as passive modulation element. To determine a relatively preferable fiber length for stable cw Q switched operation, three active fiber simples with the length of 1.1, 5.3, and 7.0 m were employed respectively in our experiments. With 1.1 m gain fiber, we generated Q switched pulses with a pulse width of 245 ns and an average power of up to 2.2 W at a repetition rate of 620 kHz. For the longer two fiber samples, Q switched operation with longer pulse duration, Q switched mode locking and cw mode locking were observed, respectively.

“…In contrast with rare earthdoped active fibres, which cannot provide generation at this band, Bi-doped fibres have shown the broad gain in the region, favourable for ultrashort pulse formation. Despite such high demand in laser sources, there are just several works on mode-locked Bi-doped fibre lasers, utilising SESAM [239,240] and CNT-based SA [61]. The first Bi-doped fibre laser to produce stable ultrashort pulses by using the SWNT-based SA was proposed and realised in 2010 [61].…”

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.

“…Generally, passive mode-locking can be achieved by using nonlinear amplifying loop mirror (NALM), nonlinear polarization rotation (NPR), and saturable absorber (SA). Due to the low gain coefficient of Bi-doped fiber used now, all the mode-locked Bi-doped fiber lasers reported so far were realized with a saturable absorber (SA) including semiconductor saturable absorber mirror (SESAM) and carbon nanotubes (CNT) [15][16][17][18][19].…”

We demonstrate a tunable and switchable dualwavelength passively mode-locked Bi-doped all-fiber ring laser by using nonlinear polarization rotation (NPR) technique. Exploiting the spectral filtering effect caused by the combination of the polarizer and intracavity birefringence, the wavelength separation of dual-wavelength mode-locked pulses can be flexibly tuned between 2.38 and 20.45 nm. Taking the advantage of NPR-induced intensity-dependent loss to suppress the mode competition, the stable dual-wavelength pulses output is obtained at room temperature. Moreover, the dual-wavelength switchable operation is achieved by simply rotating the polarization controllers (PCs).
