“…There have been many investigations regarding broadband SAs based on 2D materials, which can cover SWIR wavelengths (1550 and 1900 nm simultaneously). It should be noticed from Table 2 that the characteristics of generated pulses from SAs based on the other 2D materials such as graphene, 93 graphene oxide, 94 NbS 2 , 95 and Bi 2 O 2 S 96 vary significantly in terms of pulse duration depending on the operating wavelength. This indicates that the saturable absorption properties of those SAs are wavelength-sensitive.…”

“…The authors demonstrated that sequential sonication steps in a bath and using a tip sonicator induced the formation of 1-2 nm sized particles with enhanced fluorescence emission. Other sulfide-based MNs of great interest include WS 2 [127,128], ReS 2 [129], and NbS 2 [130], which behave similarly under ultrasound irradiation. WS 2 is another interesting case of application for the use of UATs for the production of nanometric materials that has been studied since the late 1980s [131].…”

The production of low-dimensional materials is the key topic of nanoscience. The development of new routes to downsize organic and inorganic materials has focused the attention of a great part of the scientific community that is still debating on the best route to pursue. Among nanostructures, 2D species have been investigated since the discovery of graphene. Nonetheless, the production of 2D materials is very complex, and the discussion on which is the most profitable way is still open. Ultrasound-assisted techniques represent one of the best routes for the production of 2D materials with minimum consumption of energy and best performances. Accordingly, we present a concise and exhaustive discussion about the use of ultrasound-assisted techniques for the production of both organic and inorganic 2D materials, also providing a theoretical overview of the mechanism behind the use of ultrasounds in synthetic material science.

“…In recent years, layered transition metal dichalcogenides (TMDs) as SAs have also been demonstrated; however, their applications in the nearand mid-infrared bands are limited owing to their large bandgaps in the visible waveband (MoSe 2 : %1.7 eV, MoS 2 : %1.8 eV, and WS 2 : %2.1 eV). [15][16][17][18][19][20][21][22] Hence, identifying new SA materials for Pulsed lasers have wide applications in several fields, such as basic research, telecommunications, and industrial materials processing. A saturable absorber (SA) is a key component for pulse laser generation.…”

“…In recent years, layered transition metal dichalcogenides (TMDs) as SAs have also been demonstrated; however, their applications in the near‐ and mid‐infrared bands are limited owing to their large bandgaps in the visible waveband (MoSe 2 : ≈1.7 eV, MoS 2 : ≈1.8 eV, and WS 2 : ≈2.1 eV). [ 15–22 ] Hence, identifying new SA materials for pulse laser generation is significantly important for ultrafast photonics and related applications.…”

Pulsed lasers have wide applications in several fields, such as basic research, telecommunications, and industrial materials processing. A saturable absorber (SA) is a key component for pulse laser generation. However, the current SAs exhibit certain limitations. Hence, developing new nonlinear optical materials as SAs for pulse lasers generation is significantly important in ultrafast photonics and related applications. Metallic nanomaterials have attracted considerable attention because of their higher nonlinearity coefficients and wideband nonlinear response, which are induced by the surface plasmon resonance (SPR) effect. The SPR effect depends on the size and morphology of materials. Thus, the nonlinear optical absorption effect of gold nanomaterials for pulse laser generation must be explored. In this review, the optical properties of gold nanomaterials are introduced, including SPR absorption, photoluminescence properties, and surface‐enhanced Raman scattering effect. Then, the synthesis and characterization of different gold nanomaterials are reviewed. Subsequently, the nonlinear optical characteristics and devices based on gold nanomaterials are also introduced. Furthermore, the generation of different types of lasers using gold nanomaterial‐based devices is also reviewed. A comparison between gold nanomaterials and other SA materials is presented. Finally, the conclusion and outlook on gold nanomaterial‐based nonlinear optical devices are presented.
