“…From the comparison, it is clear that our laser enabled by the TiN‐based SA shows superior performance in terms of both repetition rate and pulse width. Q‐switched pulsed lasers with high repetition rate have played an important role in the applications of photoacoustic microscopy, remote sensing and optical parametric oscillators . In our experiment, it is noteworthy that the highest repetition rate of the obtained pulsed laser is 590 kHz, which is close to the results from the recently reported new SAs based on topological insulator and graphene .…”

Ultrafast laser-induced thermalization-cooling of carriers in plasmonic nanostructures has been extensively explored in the development of high-speed photonic switches with a broad operating bandwidth. However, potential laser damage arising from the strong light-matter interaction remains a tremendous obstacle for practical applications of most colloidal processed plasmonic nanoparticles (NPs). Here, it is demonstrated that titanium nitride (TiN) NPs, with a broadband localized surface plasmon resonance in the near infrared (NIR) region, can be exploited as an ultrafast optical switch based on transient photo-bleaching, which manifests as a saturable absorption behavior with strong optical nonlinearity. The developed TiN-based optical switches exhibit high robustness against laser damage (up to peak power of 557 GW cm −2 ) and enable both Q-switched and transform-limited mode-locked pulse generation in the NIR spectral region in either fiber or solid-state lasers with pulse duration down to 763 fs. The results may stimulate further exploration of metal nitride materials for applications in nonlinear optics and ultrafast photonic devices.

“…Up to now, CNT-SA-based passively Q-switched fiber lasers can produce pulse energies over 100 nJ [53,71,[93][94][95] and even up to 1.7 μJ in Tm-doped fiber laser using a "Yin-Yang" all-fiber cavity [69], pulse durations from μs to ∼300 ns [96,97], and repetition rate up to 178 kHz [53]. Wavelength tunability can be endowed by using the tunable band pass filters [98][99][100] or gratings [71] in the related spectral regions.…”

AbstractCarbon nanotube (CNT) can work as excellent saturable absorber (SA) due to its advantages of fast recovery, low saturation intensity, polarization insensitivity, deep modulation depth, broad operation bandwidth, outstanding environmental stability, and affordable fabrication. Its successful application as SA has promoted the development of scientific research and practical application of mode-locked fiber lasers. Besides, mode-locked fiber laser constitutes an ideal platform for investigating soliton dynamics which exhibit profound nonlinear optical dynamics and excitation ubiquitous in many fields. Up to now, a variety of soliton dynamics have been observed. Among these researches, CNT-SA is a key component that suppresses the environmental perturbation and optimizes the laser system to reveal the true highly stochastic and non-repetitive unstable phenomena of the initial self-starting lasing process. This review is intended to provide an up-to-date introduction to the development of CNT-SA based ultrafast fiber lasers, with emphasis on recent progress in real-time buildup dynamics of solitons in CNT-SA mode-locked fiber lasers. It is anticipated that study of dynamics of solitons can not only further reveal the physical nature of solitons, but also optimize the performance of ultrafast fiber lasers and eventually expand their applications in different fields.

“…Before 2003, the commonly used SA for pulsed lasers was a semiconductor saturable absorber mirror (SESAM), which, however, was soon substituted by low-cost and easily synthetized carbon nanotubes (CNTs) due to the complicated fabrication process and necessary expensive facilities. Since then, different structured CNTs have been widely investigated in both Q-switching and mode-locking lasers [5,6]. Since 2004, when the single-layer carbon atom was successfully exfoliated from graphite, 2D graphene has become the most attractive SA in generating laser pulses with high performance [7][8][9].…”

By using the ultrasound-assisted liquid phase exfoliation method, Bi 2 Te 3 nanosheets are synthesized and deposited onto a quartz plate to form a kind of saturable absorber (SA), in which nonlinear absorption properties around 2 μm are analyzed with a home-made mode-locked laser. With the as-prepared Bi 2 Te 3 SA employed, a stable passively Q-switched all-solid-state 2 μm laser is successfully realized. Q-switched pulses with a maximum average output power of 2.03 W are generated under an output coupling of 5%, corresponding to the maximum single-pulse energy of 18.4 μJ and peak power of 23 W. The delivered shortest pulse duration and maximum repetition rate are 620 ns and 118 kHz under an output coupling of 2%, respectively. It is the first presentation of such Bi 2 Te 3 SA employed in a solid-state Q-switched crystalline laser at 2 μm, to the best of our knowledge. In comparison with other 2D materials suitable for pulsed 2 μm lasers, the saturable absorption performance of Bi 2 Te 3 SA is proved to be promising in generating high power and high-repetitionrate 2 μm laser pulses.
