“…For Q-switched lasers with single AOM (f A = 5 kHz) and single SnSe 2 , the shortest pulse durations of 15.8 and 119.4 ns were obtained at the pump power of 8 W, respectively. Here, the pulse durations we obtained are the shortest one ever reported in passively Q-switched lasers with SnSe 2 SA [10,14,[20][21][22][23]. To the best of our knowledge, in near-infrared region, the shortest pulse durations of 129 ns was achieved in a passively Q-switched Nd:YAG waveguide laser with SnSe 2 SA [10].…”

By simultaneously employing self-made SnSe2 saturable absorber (SA) and an acous-to-optic modulator (AOM), a dual-loss-modulated Q-switched Nd:YVO4 laser with short pulse width, high peak power and adjustable pulse repetition rate is presented. The maximum pulse peak power of 37.57 KW with the minimum pulse duration of 5.52 ns were obtained under the pump power of 8 W and the pulse repetition rate of 5 kHz. The experimental results demonstrate that the dual-loss modulation technology with AOM and SnSe2 SA is a simple and efficient method to generate short pulses with high peak power and adjustable low repetition rates.

“…Benefiting from a much shorter cavity than in active Q-switching, Zhang et al obtained short pulses, down to 6.6 ns, using a Cr:YAG saturable absorber, and a peak power of up to 9.97 kW [16]. Since then, graphene oxide [17], tungsten disulfide (WS2) [18], 2D-material (SnSe2) [19], gold nano-triangles [20], and TiS2, In order to compress laser pulse width and enhance peak power, passively Q-switched Nd:GYSGG lasers have been extensively studied with various saturable absorbers. Benefiting from a much shorter cavity than in active Q-switching, Zhang et al obtained short pulses, down to 6.6 ns, using a Cr:YAG saturable absorber, and a peak power of up to 9.97 kW [16].…”

Garnet crystals possess many properties that are desirable in laser host materials, e.g., they are suitable for diode laser (LD) pumping, stable, hard, optically isotropic, and have good thermal conductivity, permitting laser operation at high average power levels. Recently, a new garnet material, GYSGG, was developed by replacing some of the yttrium ions (Y3+) with gadolinium ions (Gd3+) in YSGG, demonstrating great potential as a laser host material. GYSGG crystals doped with trivalent neodymium ion (Nd3+) and erbium ions (Er3+) were successfully grown for laser generation in the near- and mid-infrared range, with some of the laser performances reaching the level of mature laser gain media. This paper gives an overview of the achievements made in Nd3+- and Er3+-doped GYSGG lasers at different wavelength ranges. Additionally, full descriptions on Q-switching, mode-locking and wavelength-selecting methods for Nd:GYSGG, and the mechanisms of power scaling by co-doping sensitizers and deactivators in Er:GYSGG, are given. It is expected that this review will help researchers from related areas to quickly gain an understanding of these laser materials and promotes their commercialization and applications.
