Nanomaterials have demonstrated excellent mechanical, thermal, optical, and electrical properties in various fields, including 1D carbon nanotubes, as well as 2D materials starting from graphene. Metal-based nanomaterials, mainly divided into metal and metal oxide nanoparticles, also gradually come into the sight of ultrafast photonics applications due to the outstanding optical properties. The optical properties of metal nanoparticles can be enhanced by the interaction between conduction electrons with electric fields that is called surface plasmon resonance. As for metal oxide nanoparticles, optical properties are closely related to bandgap structures. When it comes to transition metal oxides, other phenomena also play important roles in optical absorption such as spin inversion and excitons of iron. Moreover, preparation methods of materials are also crucial for their properties and further applications. Therefore, in this review, commonly used physical and chemical fabrication methods for metal-based nanomaterials are first introduced. Then the optical properties of typical metal and metal oxide nanoparticles are discussed specifically. In addition, the applications of metal-based nanomaterials in ultrafast lasers based on mode-locked and Q-switched techniques are also summarized. Finally, a summary and outlook toward the synthesis, optical properties, and applications in ultrafast photonics of metal-based nanomaterials are presented.

“…However, due to the low damage threshold of nanomaterials, the application of FONP in a solid laser has rarely been reported. Since Bai et al [12] achieved passively Q-switched output for the first time, most research on using FONP as a SA to achieve pulse output has focused on Qswitched fiber lasers [19][20][21]. After self-made and the optimization of FONP, our team reported for the first time a 1.06 µm all-solid mode-locked pulse output based on a FONP SA, and the Q-switched pulse output based on a FONP hybridized saturated absorber was realized at 1.3 µm [22,23].…”

Fe3O4 nanoparticles (FONP) are made into saturable absorbers and assembled into the resonant cavity, for the first time, and passively Q-switched mode-locked (QML) pulse output is realized in a 1.3 μm all-solid-state laser. When the pump power increases to 8 W, the repetition frequency of the Q-switched pulse increases from 47 kHz to 116 kHz, the pulse width changes from 1.137 μs to 767 ns, and the corresponding single pulse energy is 1.2 μJ. At the same time, the passively QML operation was observed on the oscilloscope, with a pulse repetition frequency of 154.5 MHz and a pulse width of 660 ps. Our experiments demonstrate that FONP exhibits good nonlinear optical characteristics in the 1.3 μm waveband, and has the potential to realize giant ultrashort and multiwavelength tunable pulse output in all-solid-state pulsed lasers.

“…Graphene [14,15] and carbon nanotubes (CNTs) [16,17] have gained more consideration due to their wide range of absorption and good compatibility with the fiber laser cavity, but they have a low damage threshold [18]. Later, topological insulators [19,20], transition metal dichalcogenides [21][22][23], black phosphorus [24,25] and metal oxides [26][27][28][29] were also demonstrated to display saturable absorption properties. By combining these materials with polymers [30], side-polished fibers [31,32], micro-fibers [33,34] or fiber facets [35], SAs were fabricated to achieve passive Q-switched laser operation.…”

We experimentally demonstrate a compact dual wavelength passive Q-switched fiber laser created by an erbium-doped fiber active medium using tellurium oxide nanoparticles (TeO 2 NPs) as a new saturable absorber (SA) material. The saturable absorption properties of the prepared TeO 2 -PVA thin film were systematically measured, and the modulation depth and saturation intensity were 8% and 90 MW cm −2 , respectively. By integrating the proposed SA in an all-fiber ring cavity, a dual wavelength laser with 1568.02 and 1569.09 nm wavelengths was observed without adding spectral filters or polarization maintaining fibers to control the suppression of the mode competition. A frequency difference of 0.13 THz was obtained located in the terahertz waveband. In the meantime, a stable Q-switched regime with a maximal pulse repetition rate of 45.7 kHz, a shortest pulse width of 2.69 µs and maximum pulse energy up to 39.4 nJ was attained at a maximum available pump power of 275 mW. The experimental setup using the TeO 2 NP SA represents a step forward in terahertz development and nonlinear optics.
