“…Now, 2D materials-based SAs, such as MoS 2 -based SA, WS 2 -based SA, TiC 2 -based SA, WSe 2 -based SA, and so on, were used as modulation devices to achieve pulse laser, and some solid laser operated at 2-μm wavelength range with excellent output performance have demonstrated in PQS mode operation in the experiment. [30][31][32][33] Compared with output performance of these solid lasers, the PQS Yb,Ho:LuVO 4 laser achieved with a SESAMs has the narrowest pulse width.…”

A continuous-wave (CW) and passively Q-switched (PQS) Yb,Ho:LuVO 4 laser pumped by a 978.6-nm laser diode (LD) is demonstrated. The maximum output power of 131 mW at 2059.78 nm in CW regime is achieved with a pump power of 3.01 W, corresponding to a slope efficiency of 10.74%. Under PQS mode operation, an average output power of 45 mW and a shortest pulse width of 100 ns were acquired by a semiconductor saturable absorber mirrors, and for all we know, this is the first report about the PQS Yb,Ho:LuVO 4 laser. In addition, a maximum energy per pulse of 12.6 nJ with a pulse repetition frequency of 7.692 MHz was obtained, corresponding to a peak power of 58.5 mW. The beam quality factor was measured to be M x 2 = 1.10 and M y 2 = 1.10 from the PQS Yb,Ho:LuVO 4 laser.

“…Tm 3+ ion-based ultrashort pulses solid lasers, which have the advantages of high pulse energy and high output power, play an important role in medical surgery, remote sensing detection, laser radar, and laser imaging. [1][2][3][4][5] Q-switched techniques including actively Q-switched and passively Q-switched (PQS) are attractive ways to realize short pulses at a 2-µm wavelength range. By comparison with actively Q-switched technology, PQS lasers combined with a saturable absorber (SA) have been proved to be a simple, compact, and low-cost way in which to be extensively employed to obtain nanosecond-or microsecond-level lasers.…”

A saturable absorber based on a novel two-dimensional (2D) material Bi 2 O 2 Se was placed in a resonator with an overall longest diameter of 31 mm to achieve efficient operation of a passively Q-switched (PQS) Tm:YAP laser for the first time. In PQS mode, a 1.62-W average output power with a pulse width of 1.24 µs and a pulse repetition of frequency of 112.1 kHz was achieved at the pump power of 22.2 W, corresponding to a peak power of 11.66 W. As a novel 2D material, the results show the potential of Bi 2 O 2 Se as a photomodulator in the 2 µm spectral range.

Pulsed solid‐state lasers comprise 2D materials as saturable absorbers that contain transparent windows of the atmosphere and characteristic fingerprint spectra of several vital molecules that are significant in various applications and research. Over the past few decades, significant progress has been made in the development of narrow pulse width, high energy, high average output power, high efficiency, and simple construction of passively Q‐switched and mode‐locked lasers with 2D materials as saturable absorbers. This review summarizes the development of 2D materials, including graphene, transition metal dichalcogenides, black phosphorus, topological insulators, and MXenes, as modulator devices for solid‐state lasers owing to their broadband operation, excellent nonlinear optical response, low recovery time, ultrafast dynamic processing, and easy fabrication. Then, some new emerging and representative applications of pulsed solid‐state lasers are introduced and illustrated such as laser surgery, material processing, and lidar. Finally, future challenges and perspectives of pulsed solid‐state lasers with 2D materials‐based saturable absorbers are analyzed and addressed. The rapid development of pulsed solid‐state lasers with the continuous improvement of modulation technology is expected to expand opportunities for application in industry, scientific, medical, and other areas.
