“…However, to achieve the 1.4 μm laser operation, stringent requirements should be fulfilled, such as a high-finesse cavity and good suppression of the 1.3 μm laser oscillation. The first Nd:GYSGG laser in the 1.3-1.35 μm wavelength range was reported in 2012 [31]. Using a diode-end-pumped plane-parallel cavity with different out-coupling efficiencies of 8.4 and 6.0%, single-wavelength operation at 1336 nm and dual-wavelength operation at 1321/1336 nm with a minor wavelength at 1330 nm were achieved with variable power proportions according to the pump intensity.…”

“…Although AO Q-switching is a conventional and preferred approach for generating stable laser pulses, passive Q-switching is sometimes superior due to its narrower pulse width and higher peak power with a much shorter cavity.

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.

“…The laser characteristics researches of Nd:GYSGG have achieved great breakthrough, recently. For example, the continuous wave (CW), acousto‐optic (A‐O) and passively Q‐switch laser performance of Nd:GYSGG with dual‐wavelength output at 1061.5 nm and 1058.4 nm has been reported by K. Zhong et al . The mode‐lock laser performance of Nd:GYSGG with a single wavelength at 1061 nm has been demonstrated by B.Y.…”

In the present work, we investigated the mechanical properties (including hardness, fracture toughness, brittleness index and yield strength) of Nd 0.03 Gd 0.93 Y 2.04 Sc 2 Ga 3 O 12 (Nd:GYSGG) laser crystal using Vickers microhardness tester, for the first time. The defects morphology of Nd:GYSGG crystal were investigated by using chemical etching method with phosphoric acid etchant. The absorption spectrum of Nd:GYSGG from 300 to 2800 nm was measured at room temperature and the absorption peaks were assigned. The fluorescence lifetime of the 4 F 3/2 → 4 I 11/2 transition of Nd 3+ in GYSGG is fitted to be 221.3 μs. The three Judd-Ofelt intense parameters 2, 4, 6 were calculated to be 0.329 × 10 −20 cm 2 , 2.761 × 10 −20 cm 2 and 4.222 × 10 −20 cm 2 , respectively. All these demonstrate that Nd:GYSGG crystal is a good candidate laser material.

“…Most recently, Xu reported the self-Qswitched dual-wavelength operation of the Yb: CGB crystal [18]. With an inhomogeneous broadening of the emission spectra, lower emission cross-sections (1.58 × 10 −19 cm 2 ), and longer upper laser level lifetime (220 μs), Nd:GYSGG crystal is beneficial to generate dual-wavelength and high energy Q-switched laser pulses [19,20]. However, there is no report about the SQS operation of the Nd:GYSGG crystal with dual-wavelength.…”

A dual-wavelength self-Q-switched operation of Nd:GYSGG laser with different output couplers is proposed and demonstrated. In self-Q-switched operation, two laser lines between 1056.86 nm and 1060.23 nm were found. Under the pump power of 4 W, the shortest pulse width of 2.02 μs was obtained with a maximum average output power of 565 mW and the optical conversion efficiency of 14.13%. The pulse repetition rate and single pulse energy were 50.2 kHz and 11.25 μJ, respectively. The system is very stable and suitable for generation of multi-wavelength pulses.
