“…By taking advantage of the strong nonlinear effect in perovskites, Q‐switched and mode‐locking fiber lasers have been realized, [ 149–156 ] in which perovskite serves as saturable absorber. As illustrated in Figure 9h, perovskite nanocrystal film is incorporated into the fiber ring resonator and modulates the output laser.…”

In the past decade, lead halide perovskites have been intensively explored due to their promising future in photovoltaics. Owing to their remarkable material properties such as solution processability, nice defect tolerance, broad bandgap tunability, high quantum yields, large refractive index, and strong nonlinear effects, this family of materials has also shown advantages in many other optoelectronic devices including microlasers, photodetectors, waveguides, and metasurfaces. Very recently, the stability of perovskite devices has been improved with the optimization of synthesis methods and device architectures. It is widely accepted that it is the time to integrate all the perovskite devices into a real system. However, for integrated photonic circuits, the shapes and distributions of chemically synthesized perovskites are quite random and not suitable for integration. Consequently, controlled synthesis and the top‐down fabrication process are highly desirable to break the barriers. Herein, the developments of patterning and integration techniques for halide perovskites, as well as the structure/function relationships, are systematically reviewed. The recent progress in the study of optical responses originating from nanostructured perovskites is also presented. Lastly, the challenges and perspective for nanostructured‐perovskite devices are discussed.

“…The oxygen vacancy formation energy, Ef(Ov), a commonly used descriptor of the reducibility of surface lattice oxygen with different coordination environments was calculated through the formula Ef(Ov) = Edef -Efree + ½ EO2, in which Edef, Efree, and EO2 are the energies of the defective structure with an oxygen vacancy, the perfect system, and the free molecular oxygen, respectively. 48 Fig. 7 describes the surface chemical status of these CaxMnyOz samples.…”

“…The former is expensive and difficult to manufacture, while the latter has not only a narrow operation wavelength band but a high pumping threshold [19]. In recent years, two-dimensional (2D) materials have been used more and more in the field of Q-switched laser pulse generation due to their advantage of compactness, low-cost, and convenience [20][21][22][23][24][25][26][27][28].…”

In this work, we successfully fabricated a transmissive saturable absorber (SA) with Ti2CTx MXene using the spin-coating method. By inserting the Ti2CTx saturable absorber into the diode-pumped solid-state (DPSS) Nd:YAG laser, a stable passively Q-switched operation was obtained near 1.06 μm. At a pump power of 4.5 W, we obtained the shortest pulse duration of 163 ns with a repetition rate of 260 kHz. The corresponding single pulse energy and peak pulse power were 3.638 μJ and 22.3 W, respectively. The slope efficiency and the optical conversion efficiency of the laser were 21% and 25.5%, respectively. To the best of our knowledge, this is the first time that Ti2CTx was used in the passively Q-switched solid-state lasers. This work demonstrates that Ti2CTx can be a promising saturable absorber for solid-state laser pulse generation.
