“…However, mode-locked fiber lasers based on NPR and the NALM technique are intrinsically environmentally unstable. Therefore, researchers have strong motivations investigate HML in passively mode-locked fiber lasers by real saturable absorbers (SAs) [11][12][13][14][15][16], such as semiconductor saturable absorbers (SESAM), single-walled carbon nanotube (SWNT) and graphene. However, these SAs also possess some inherent drawbacks.…”

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.

“…SESAMs generally have a limited bandwidth which results from their resonant design and require complex semiconductor fabrication processes, packaging and integration 22 . Recently, a new generation of saturable absorber (SA) based on 1D (carbon nanotubes, CNTs) or 2D (such as graphene, MoS 2 and black phosphorous) nanomaterials have come into prominence 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 . These nanomaterial-based SAs have the advantages through easy and economic fabrication and when in composite form, transmission-type operation for simple integration into all-fiber ring cavities 33 39 .…”

Ultrafast fiber lasers with broad bandwidth and short pulse duration have a variety of applications, such as ultrafast time-resolved spectroscopy and supercontinuum generation. We report a simple and compact all-fiber thulium-doped femtosecond laser mode-locked by carbon nanotubes. The oscillator operates in slightly normal cavity dispersion at 0.055 ps2, and delivers 152 fs pulses with 52.8 nm bandwidth and 0.19 nJ pulse energy. This is the shortest pulse duration and the widest spectral width demonstrated from Tm-doped all-fiber lasers based on 1 or 2 dimensional nanomaterials, underscoring their growing potential as versatile saturable absorber materials.

“…Among 2D materials, graphene has earlier been applied to the preparation of SAs [20][21][22][23][24][25]. Based on graphene SAs, researchers have obtained mode-locked pulses at 1 μm, 1.5 μm, 2 μm, and 2.5 μm [26][27][28][29][30][31][32].…”

Tungsten disulfide saturable absorbers for 67 fs mode-locked erbium-doped fiber lasers

et al. 2017

View full text Add to dashboard Cite

In this paper, we demonstrate 67 fs pulse emitting with tungsten disulfide (WS₂) in mode-locked erbium-doped fiber (EDF) lasers. Using the pulsed laser deposition method, WS₂ is deposited on the surface of the tapered fiber to form the evanescent field. The fiber-taper WS₂ saturable absorber (SA) with the large modulation depth is fabricated to support the ultrashort pulse generation. The influences of the WS₂ SA are analyzed through contrastive experiments on fiber lasers with or without the WS₂ SA. The pulse duration is measured to be 67 fs, which is the shortest pulse duration obtained in the mode-locked fiber lasers with two dimensional (2D) material SAs. Compared to graphene, topological insulator, and other transition metal dichalcogenides (TMDs) SAs, results in this paper indicate that the fiber-taper WS₂ SA with large modulation depth is a more promising photonic device in mode-locked fiber lasers with the wide spectrum and ultrashort pulse duration.
