“…Experiments were conducted to investigate the influence of graphene layers from 1 to 15 layers [99], 3 to 12 layers [88], and 9 to 48 layers [17] on the MD. Based on these articles, higher MD was obtained with thicker graphene layers as presented in Fig.ure 6.…”

“…A rotary pump vacuum oil was deployed as the carbon source in synthesizing a CVD-grown graphene [99]. During this process, a Cu foil substrate is placed into a tubular furnace and was evacuated to ~3 mTorr by a rotary pump, whereas the sample was heated to 1000 °C for 30 minutes.…”

“…Such SAs have large modulation depths, while they are designed to operate at certain wavebands. Recently, two-dimensional nanomaterials, ranging from graphene [15][16][17], topological insulators [18][19][20], and transition metal dichalcogenides [21][22][23][24][25], to black phosphorus [26][27][28] have been proven to exhibit an ultrafast saturable absorption property. By incorporating such materials with polymer [29,30], micro-fiber [19], side-polished fiber [31,32], or fiber facets [33], various types of SAs were fabricated to achieve passively Q-switched operation or mode-locked operation.…”

We demonstrate that ferroferric-oxide (Fe 3 O 4) nanoparticles exhibit nonlinear saturable absorption property at 1.55 μm, and fabricate two filmy saturable absorbers by embedding the nanoparticles into a polyvinyl alcohol (PVA) film or polyimide (PI) film separately. In the Fe 3 O 4-PVA (Fe 3 O 4-PI) Q-switched fiber laser, the pulse repetition rate increases from 8.5 kHz (5.5 kHz) to 28 kHz (49 kHz) and the pulse duration decreases from 23.5 μs (47 μs) to 6 μs (3.5 μs) by varying the pump power from 25 mW (23 mW) to 150 mW (650 mW). Experiment results indicate that PI-based saturable absorbers can afford larger powers than PVA-based saturable absorbers, which can be attributed to the higher fusion point of the PI film. The Fe 3 O 4-PI saturable absorber exhibits features of high damage threshold, low cost, and good flexibility, which could be applied in fields of near-infrared pulse generation and frequency conversions.

“…For passively MLFLs, a saturable absorber (SA) is indispensable in shaping the pulses in the temporal domain2. Among the various types of SAs, semiconductor saturable absorber mirror (SESAM)13, single-wall carbon nanotubes (SWCNTs)45678, and graphene910111213 were intensively used in various MLFL schemes. Although SESAMs have been mostly used in laser resonators to generate mode-locked laser pulses, they are expensive, complicated in fabrication processes (e.g., grown on lattice-matched semiconductor substrates with high quality distributed Bragg reflector mirror), and narrow in wavelength tuning range (typically a few tens of nanometers)1.…”

A novel high-quality, large-size, reflection-type topological insulator Bi2Te3-Gold (BG) film-based nonlinear optical modulator has been successfully fabricated as a two-dimensional saturable absorber mirror (SAM) by pulsed laser deposition (PLD). This BG-SAM possesses saturation fluence of 108.3 μJ/cm2, modulation depth (ΔR) of 6.5%, non-saturable loss of 38.4%, high damage threshold above 1.354 mJ/cm2 and excellent uniformity providing for the generation of passive mode-locked (ML) pulses for erbium-doped fiber lasers (EDFLs) on a large sample area. Under 124 mW 976 nm pumping, We obtained 452-fs continuous-wave ML pulses with pulse energy of 91 pJ and full width at half-maximum (FWHM) of 6.72-nm from this EDFL. The results clearly evidence that the PLD is an efficient method for fabricating BG-SAM that is suitable for a compact ultrafast ML fiber laser system.
