“…MoWSe2 SA performance did not show any degradation over time, demonstrating its potential and applicability as a novel 2D broadband SA material [81]. Yin et al reported the first realisation of femtosecond photonics of Mo0.5W0.5S2 SA in 2022, suggesting that it is a good candidate for the mode-locked ultrafast fibre laser for optoelectronic and optical communication applications [82]. Niu et al prepared 2D MoWS2 by using the CVD method and liquid-phase glass method and proposed an LD-pumped doubly Q-switched mode-locked (QML) Tm:YAP laser at a waveband…”

Two-dimensional (2D) transitional metal dichalcogenides (TMDs) have garnered remarkable attention in electronics, optoelectronics, and hydrogen precipitation catalysis due to their exceptional physicochemical properties. Their utilisation in optoelectronic devices is especially notable for overcoming graphene’s zero-band gap limitation. Moreover, TMDs offer advantages such as direct band gap transitions, high carrier mobility, and efficient switching ratios. Achieving precise adjustments to the electronic properties and band gap of 2D semiconductor materials is crucial for enhancing their capabilities. Researchers have explored the creation of 2D alloy phases through heteroatom doping, a strategy employed to fine-tune the band structure of these materials. Current research on 2D alloy materials encompasses diverse aspects like synthesis methods, catalytic reactions, energy band modulation, high-voltage phase transitions, and potential applications in electronics and optoelectronics. This paper comprehensively analyses 2D TMD alloy materials, covering their growth, preparation, optoelectronic properties, and various applications including hydrogen evolution reaction catalysis, field-effect transistors, lithium-sulphur battery catalysts, and lasers. The growth process and characterisation techniques are introduced, followed by a summary of the optoelectronic properties of these materials.

“…Since atomic layer graphene was discovered in 2004 [6] and ultrafast fiber lasers based on graphene were first demonstrated in 2009 [7], the research on two-dimensional (2D) nanomaterials in the field of ultrafast lasers has been started [8]. A variety of 2D nanomaterials [9], such as black phosphorus (BP) [10,11], topo-logical insulators (TIs) [12,13], MXene [14,15], III-V compound layered semiconductors [16,17], and transition metal dichalcogenides (TMDs) [18][19][20][21], have become the research hotspots of SA. Compared with the commonly used semiconductor saturable absorber mirror (SESAM), these 2D nanomaterials were relatively ideal SA materials due to their wide-band response and excellent nonlinear optical (NLO) characteristics.…”

This paper systematically studied the composition-controlled nonlinear optical properties and pulse modulation of ternary ReS2(1-x)Se2x alloys for the first time. The compositionally modulated characteristics of ReS2(1-x)Se2x on the band gap were simulated based on the first principles. We investigated the effect of the band gap on the saturable absorption properties. In addition, we demonstrated the modulation characteristics of different components ReS2(1-x)Se2x on 1.5 μm Q-switched pulse performance. The Q-switched threshold, repetition rate, and pulse duration increase as the S(sulfur)-element composition rise. And pulse energy also was affected by the S(sulfur)-element composition. The ReS0.8Se1.2 SA was selected to realize a conventional soliton with high energy in the all-fiber mode-locked laser. The pulse was centered at 1562.9 nm with a pulse duration of 2.26 ps, a repetition rate of 3.88 MHz, and maximum pulse energy of 1.95 nJ. This work suggests that ReS2(1-x)Se2x has great potential in laser technology and nonlinear optics, and widely extends the material applications in ultrafast photonics.

“…In the following year, a passively Q-switched Tm/Ho-co-doped fiber laser at 2.0 µm was proposed [20]. In 2022, a mode-locked Er-doped fiber laser with a pulse duration of 575-800 fs was obtained, with ternary 2D MoWS 2 as a SA [21]. Niu et al presented a Q-switched mode-locked Tm:YAP laser at 2 µm using MoWS 2 nanosheets [22].…”

In this paper, the laser diode (LD)-pumped all-solid-state Yb:YSr3 (PO4)3 (Yb:YSP) lasers with active and passive Q-switching operation were demonstrated for the first time. At the pump power of 5.5 W, the average output power was 369 mW and the single pulse energy was 184.5 μJ at 2 kHz in the active Q-switching operation with an optical chopper. For the acousto-optic modulator Q-switched laser, a 118 ns pulse duration and 2881 W pulse peak power at 0.5 kHz were obtained. Furthermore, MoWS2 nanosheets were implemented to the passively Q-switched Yb:YSP laser, generating stable pulses with duration of 1.45 μs at the repetition frequency of 55 kHz and verifying the optical response potential of MoWS2. The good laser beam quality of M x 2 = 1.14 and M y 2 = 1.12 were achieved as well.
