“…4(b), which gives a signal-to-noise ratio of around 45 dB for the generated peaks. This shows that the output pulses are highly stable [37] and comparable to those obtained using other types of SAs in similar configurations [1,38,39] . Furthermore, expanding the frequency span until 1 MHz, as shown as the inset of Fig.…”

Passively Q-switched ytterbium-doped fiber lasers (YDFLs) incorporating a molybdenum sulfide selenide (MoSSe)-based saturable absorber (SA) are demonstrated. The modulation depth and saturation intensity of the MoSSe-based SA are measured to be approximately 25.0% and 0.002 MW∕cm 2 , respectively, using the twin detector technique. The YDFL's output has a center wavelength of 1038.5 nm with a top pulse width and energy of 1.2 μs and 18.9 nJ, respectively, at a pump power of 333 mW. The MoSSe-based SA has a good linear optical response, providing significant opportunity for use in applications over an ultra-broadband spectrum, particularly spectroscopy and biomedical diagnostics.

“…At the same time, they have been successfully utilized as SA for the realization of mode-locking [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. TISA could be fabricated by the mechanical exfoliation, the molecular beam epitaxy (MBE) growth, the vapor-liquidsolid growth, chemical exfoliation, the mechanical triturating and the filmy method in polyvinyl alcohol [25,[42][43][44]. In most of recent studies, the nanostructured TIs are typically deposited onto the fiber ferrule [23,28,29,45].…”

We reported that the photonic crystal fiber (PCF) filled with TI:Bi2Te3 nanosheets solution could act as an effective saturable absorber (SA). Employing this TI-PCF SA device; we constructed an ytterbium-doped all-fiber laser oscillator and achieved the evanescent wave mode-locking operation. Due to the large cavity dispersion; the fundamental mode-locking pulse had the large full width at half maximum (FWHM) of 2.33 ns with the repetition rate of ~1.11 MHz; and the radio frequency (RF) spectrum with signal-to-noise ratio (SNR) of 61 dB. In addition; the transition dynamics from a bunched state of pulses to harmonic mode-locking (HML) was also observed; which was up to 26th order.

“…For example, the paper reported by Luo et al [14] using molybdenum disulphide (MoS2) as SA produced shortest pulse duration of 5.4 μs. Topological insulators as passive saturable absorber was demonstrated using bismuth selenide (Bi2Se3) and bismuth telluride (Bi2Te3), yielding pulse width of 1.9 μs and 13 μs respectively [15,16]. The repetition rate and the average output power of the pulsed laser increases with the increasing pump power.…”

Abstract. The paper demonstrates passively Q-switched erbium-doped fiber laser implementing multiwalled carbon nanotubes (MWCNTs) based saturable absorber. The paper is the first to report the use of the MWCNTs with diameter less than 8 nm as typically, the diameter used is 10 to 20 nm. The MWCNTs is incorporated with water soluble host polymer, polyvinyl alcohol (PVA) to produce a MWCNTs polymer composite thin film which is then sandwiched between two fiber connectors. The fabricated SA is employed in the laser experimental setup in ring cavity. The Q-switching regime started at threshold pump power of 103 mW and increasable to 215 mW. The stable pulse train from 41.6 kHz to 76.92 kHz with maximum average output power and pulse energy of 0.17 mW and 3.39 nJ are produced. The shortest pulse width of 1.9 s is obtained in the proposed experimental work, making it the lowest pulse width ever reported using MWCNTs-based saturable absorber.
