Owing to their extraordinary physical and chemical properties, two-dimensional (2D) materials have aroused extensive attention and have been widely used in photonic and optoelectronic devices, catalytic reactions, and biomedicine. In particular, 2D materials possess a unique bandgap structure and nonlinear optical properties, which can be used as saturable absorbers in ultrafast lasers. Here, we mainly review the top-down and bottom-up methods for preparing 2D materials, such as graphene, topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes. Then, we focus on the ultrafast applications of 2D materials at the typical operating wavelengths of 1, 1.5, 2, and 3 μm. The key parameters and output performance of ultrafast pulsed lasers based on 2D materials are discussed. Furthermore, an outlook regarding the fabrication methods and the development of 2D materials in ultrafast photonics is also presented.

“…schemes as well, and they can dramatically extend the applications of optoelectronics devices [1][2][3][4]. ZnSe and ZnS materials can be considered as perspective semiconductors to form the different detectors for the wide spectral range and to develop the mirrors and the optical limiting instruments [5][6][7][8][9][10][11][12][13][14][15][16][17]. Researchers have revealed the anti-reflective, luminescent properties of these materials and visualized the process of the nanoparticles' creation based on the ZnSe and ZnS structures and their introduction into the polymer matrices [8][9][10][11].…”

It is known that a material’s volume and the surface structuring by the nanoparticles causes a significant change in the material’s basic properties. In this aspect, the structuration of the surface of semiconductors is of interest, because their wide potential application in optoelectronics can extend the products’ transparency, hardness, wettability, and other important parameters. This paper presents possible methods for the surface modification of zinc selenide and zinc sulfide when carbon nanotubes are deposited on the surface by the application of the laser-oriented technique. It also shows changes of the spectral, mechanical, and wetting characteristics of the considered materials. Using the molecular dynamic simulations, the possible process of the carbon nanotubes penetration into the considered surfaces is presented. The simulation results are partially supported by the obtained experimental data.

“…This can be achieved by developing high‐power, femtosecond 2 µm lasers based on Tm 3+ ‐, [ 45 ] Ho 3+ ‐, [ 46 ] or Cr 2+ ‐doped [ 47,48 ] crystals and its subsequent nonlinear conversion to the longer wavelength range [ 49 ] or by direct dual‐comb generation from Fe 2+ lasers up to 6 µm. [ 47,50 ] Consequently, the reported technique paves the way for a new class of single‐cavity dual‐comb lasers, which, due to their low‐noise free‐running operation, will enable spectroscopic measurements without any active stabilization in the near future.…”

Dual‐comb spectroscopy is a rapidly developing technique enabling ultraprecise broadband optical diagnostics of atoms and molecules. This powerful tool typically requires two phase‐locked femtosecond lasers, yet it has been shown that it can be realized without any stabilization if the combs are generated from a single laser cavity. Still, unavoidable intrinsic relative phase fluctuations always set a limit on the precision of any spectroscopic measurements, hitherto limiting the applicability of bulk dual‐comb lasers for mode‐resolved studies. Here, a versatile concept for low‐noise dual‐comb generation from a single‐cavity femtosecond solid‐state laser based on intrinsic polarization‐multiplexing inside an optically anisotropic gain crystal is demonstrated. Due to intracavity spatial separation of the orthogonally polarized beams, two sub‐100 fs pulse trains are simultaneously generated from a 1.05 µm Yb:CNGS (calcium niobium gallium silicate) oscillator with a repetition rate difference of 4.7 kHz. The laser exhibits the lowest relative noise ever demonstrated for a bulk dual‐comb source, supporting free‐running mode‐resolved spectroscopic measurements over a second. Moreover, the developed dual‐comb generation technique can be applied to any solid‐state laser exploiting a birefringent active crystal, paving the way toward a new class of highly coherent, single‐cavity, dual‐comb laser sources operating in various spectral regions.
