“…Among them, passive Q-switching technology based on saturable absorber (SA) has made remarkable progress in view of compact, low cost, flexible, and so on. Since the Nd:glass (the first generation of SA) was successfully used for pulse generation in 1966 [7], a wide variety of SAs have been intensively developed, such as Semiconductor Saturable Absorption Mirrors (SESAMs) [8,9], Carbon Nanotubes (CNTs) [10][11][12][13], graphene [14][15][16][17][18], Topological Insulator (TI) [19,20], and Transition Metal Dichalcogenides (TMDs) [21][22][23][24]. The SESAMs are utilized in most of commercially available laser systems for high flexibility and stability.…”

“…However, SESAMs have relatively narrow operation bandwidth and require complex fabrication and packaging [1]. Recently, the research on broadband SAs based on CNT or graphene has presented explosive development for broad operation bandwidth, ultrafast recovery times, low saturation intensity, low cost, and easy fabrication [10][11][12][13][14][15][16][17][18]. Nevertheless, they still have some drawbacks.…”

“…Nevertheless, they still have some drawbacks. The spectral response range of CNTs sensitively depends on their diameter and chirality, restricting their practical applications in specific wavelength or broadband tenability [13]. And, graphene has relatively weak optical absorption (∼2.3%/layer [20]) due to its gapless band structure, which limits its application in fiber laser.…”

Black phosphorus (BP), a new two-dimensional (2D) material, has been deeply developed for extensive applications in electronics and optoelectronics due to its similar physical structure to graphene and thickness dependent direct band gap. Here, we demonstrated a submicrosecond passive Q-switching Er-doped fiber laser with BP as saturable absorber (SA). The BP saturable absorber was fabricated by mechanical exfoliation method. By taking full advantage of the ultrafast relaxation time of BP-SA and careful design of compact ring cavity, we obtained stable Q-switching pulses output with a shortest duration as narrow as 742 ns. With increasing the pump power, the pulse repetition rate accreted gradually almost linearly from 9.78 to 61.25 kHz, and the pulse duration declined rapidly at lower pump power regime and retained approximate stationary at higher pump power regime from 3.05 to 0.742 s. The experimental results indicate that BP-SA can be an effective SA for nanosecond Q-switching pulse generation.

“…There are two main techniques, active [4,5] or passive [6], to generate Q-switched pulses. As compared to actively Q-switched fibre lasers, passive laser systems have a number of advantages, in particular a simpler setup and less bulkiness [7], which are suitable for small foot-print applications.…”

Abstract.We have developed and approved experimentally a passively Q-switched erbium-doped fibre laser. It is based on the saturable absorption of graphene oxide solution deposited around a microfibre waveguide. The microfibre is fabricated using a standard flame-brushing technique. By controlling the pump power in the cavity, the fibre laser can produce microsecond Q-switched pulses at 1529 nm with the maximum repetition rate 53.47 kHz. With a pumping power of 105.98 mW at 980 nm, each of the laser pulses has the energy about 0.78 nJ and the maximum output power is 42.15 μW.

“…Up to date, many works have been reported on the integration of SWCNT/polyvinyl alcohol (PVA) SAs into fibre laser systems for ultra-short pulse generation (see, e.g., [8]). However, most of the works involving the SWCNT-based SAs have been directed at building mode-locked fibre lasers [9,10], while Q-switched fibre lasers have been addressed seldom enough [11]. Besides, a few works reported on the Q-switched lasers have been focused mainly on single-wavelength operation [2,11].…”

Abstract.A stable passively Q-switched multi-wavelength erbium-doped fibre laser operating near 1533.5 nm is demonstrated using a saturable absorber based on single-walled carbon nanotube film, which is prepared using polyvinyl alcohol as a host polymer. The laser achieves a multi-wavelength oscillation regime as a result of nonlinear polarization rotation effect, which overcomes unstable mode competition in the ring cavity. It generates a stable multi-wavelength comb of seven lines, with the wavelength spacing of 0.10 nm at the pump power 64 mW. At the same pump power, the laser produces a stable pulse train with the repetition rate 13.1 kHz, the pulse width 7.2 µs and the pulse energy 21 nJ. A high performance of our Qswitched laser is achieved by optimizing the saturable absorber and the laser cavity.
