“…Meanwhile, the pulse width decreased linearly from 8.68 μs to 3.4 μs. These trends prove the typical characteristics of Q-switching operation [18]. Figure 11 shows the peak power and energy variations of the generated pulse.…”

“…Recent researches have reported many alternatives for the saturable absorption materials such as the transition metal dichalcogenides (TMDs) and the topological insulators (TIs), for instance, bismuth selenide (Bi2Se3) [13][14], molybdenum disulphide (MoS2) [15], molybdenum selenide (MoSe2) [16] and tungsten disulphide (WS2) [17]. Metal nanoparticles such as gold and silver based SAs are also the excellent candidates [18][19]. Nevertheless, graphene is still the most favourable SA as it has the ultimate potentials for the implementation of the efficient pulsed fiber lasers and solid-state lasers [20][21][22][23][24][25].…”

This paper reported a successful demonstration on Q-switched fiber laser by using graphite as saturable absorber (SA). The graphite is deposited on the fiber ferrule through a simple mechanical exfoliation method. The modulation depth of the graphite SA is 19.2% with a saturation intensity of 85 MW/cm². The maximum achievable pulse repetition rates and pulse width are 42.41 kHz and 3.40 μs respectively. Meanwhile, its optical signal-to-noise ratio is about 50.81 dB. The Q-switched pulses have the maximum pulse energy of 5.84 nJ. These outcomes demonstrated that a stable output of passively Q-switched fiber laser is produced and can be applied for various optical fiber applications.

“…Fan et al have reported a passively Q-switched EDFL using evanescent field interaction with a GNPs SA [22]. In addition, passively Q-switched fiber lasers at 635 nm using filmy GNPs as SAs and at 1 μm waveband using filmy GNRs as SAs have also been experimentally demonstrated [23,24]. These results indicate that gold nanomaterials are promising SAs for ultrafast pulse generation.…”

“…In recent years, gold nanomaterials, including gold nanoparticles (GNPs) and gold nanorods (GNRs), have been proposed as SAs for constructing Q-switched fiber lasers owing to their outstanding optical properties including large third-order nonlinearity, broadband absorption, and fast response, which arise mainly from the localized surface plasmon resonance (SPR) [20][21][22][23][24]. SPR is an optical phenomenon related to the coherent oscillations of electron plasmas at the surfaces of metallic particles.…”

In this paper, we propose and demonstrate an all-fiber passively Q-switched erbium doped fiber laser (EDFL) by using gold nanostars (GNSs) as a saturable absorber (SA) for the first time, to the best of our knowledge. In comparison with other gold nanomorphologies, GNSs have multiple localized surface plasmon resonances, which means that they can be used to construct wideband ultrafast pulse lasers. By inserting the GNS SA into an EDFL cavity pumped by a 980 nm laser diode, a stable passively Q-switched laser at 1564.5 nm was achieved for a threshold pump power of 40 mW. By gradually increasing the pump power from 40 to 120 mW, the pulse duration decreases from 12.8 to 5.3 μs and the repetition rate increases from 10 to 17 kHz. Our results indicate that the GNSs are a promising SA for constructing pulse lasers.

“…By varying the aspect ratio of GNRs, it is possible to shift the linear and the nonlinear absorption behavior, which is the focus of theoretical and experimental research [26]. By controlling the aspect ratio of the GNRs, the longitudinal SPR absorption peaks can be located at 800-1500 nm, making it possible to act as a SA to achieve the desired mode-locked laser output [27]- [29]. When it comes to the fiber laser modulated by the SA, the method on how to integrate the nonlinear optical material into the fiber laser cavity is very important.…”

We demonstrated the dissipative soliton generation from a passively modelocked ytterbium-doped fiber laser operating at 1041 nm by using evanescent field interaction with gold nanorods (GNR) saturable absorber (SA) experimentally. The GNRs, which have broadband longitudinal surface plasmon resonance absorption from ∼800 to ∼1500 nm, are synthesized by a seed-mediated growth method, and then composited with a D-shaped fiber to form the GNRs SA. The GNRs SA shows a modulation depth of 9.7% and low saturation intensity of 0.302 MW/cm 2 . With the proposed GNRs SA, a dissipative soliton fiber laser was achieved with pulse duration 162.3 ps, repetition rate of 6.649 MHz at 1041 nm for a pump power of 220 mW. In addition, the signal-to-noise ratio can reach ∼77 dB. The experimental result may make inroads for the nonlinear optical applications of the plasmonic nanomaterials.
