“…Optical limiting has different origins: RSA which takes place due to enhanced absorption is responsible for optical limiting in metal compounds and fullerenes and 2 PA is responsible for optical limiting in semiconductor structures. One of the main sources of optical nonlinearities is the excited-state-induced process, which has potential application for optical limiting; study of these states in terms of enhanced populations of various optical nonlinear solutions is worth continuing by using variation among sizes of their nonlinear optical responses at off-resonant conditions [40]. Optical limiting behavior can be enhanced by choosing the appropriate parameters, such as detuning and the tunneling rate, from which the system will reveal good optical limiting properties in certain intensity regions which can be attributed to an RSA mechanism.…”

The strong nonlinear optical behavior of low-dimensional materials, such as quantum dots and core-shell quantum dots, has been a topic of intense research in recent years. As quantum dots have tunable emission via changes in their sizes, they are potentially useful in photo-electronics, photovoltaic nonlinear optics, light-emitting diode fabrication, and laser protections. Variation among core and shell shape and size, along with the chemical composition of quantum dots, define their enhanced nonlinear optical properties. Some specific nonlinear optical properties, such as nonlinear refraction, optical limiting, saturable absorption, reverse saturable absorption of CdTe and CdSe quantum dots (QDs), as well as core-shell QDs and their applications, were assessed in this paper.

“…From Figure 2a, we see that the transmittance of RPPSU and BPPSU first decrease and then increase along the direction of Z ‐scan, showing the typical shape of the valley, which conforms to the characteristics of RSA. [ 26,27 ] According to the curve, the normalized transmittance of RPPSU and BPPSU decreased to 0.97 and 0.95, respectively, which means that the valley of BPPSU is deeper and shows better NLO performance. This is mainly due to the fact that the amino group in the anthraquinone chromophore of BPPSU can be used as an electron donor group, while p ‐benzoquinone functions as an electron acceptor group.…”

In a previous study, three kinds of polymers are synthesized by the covalent bonding of three anthraquinone chromophores to polyphenylene sulfone. Herein, the nonlinear optical (NLO) properties of solutions and thin films of anthraquinone‐containing polyphenylsulfone, which can function as effective optical limiting materials are discussed in detail. The reasons for the improved NLO properties of the thin films are explained from the perspective of chromophore content, polarization orientation, and energy level transition. In addition, the NLO properties thermal stability and chemical stability of the three polymers are tested. The results show that the three types of polyphenylsulfone materials have excellent optical limiting properties. Further, since the nonlinear optical coefficient decreases by less than 8% after treatment by heat and acid or basic solutions, they exhibit excellent nonlinear optical stability.

“…[96] Recently, Fu et al also investigated the size-dependent nonlinear optical properties of chemically prepared GNP suspensions using femtosecond pulses, as shown in Figure 18. [97] Moreover, other nonlinear optical effects, such as the Kerr effect and third-harmonic generation in GNPs were also studied. [98][99][100][101] Figure 19 shows the third-harmonic generation in GNPs.…”

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.
