“…For the same purpose, and following a similar approach to Nd:GYSGG, another new category of laser materials-the Er:GYSGG crystals-have been grown by the Czochralski method. These crystals possess the main physical and anti-radiation merits of Nd:GYSGG [8]. Different ions can be used as sensitizers and deactivators to enhance the LD-to-laser conversion efficiency and overcome the self-terminating "bottleneck" effect.…”

“…The properties of Er:GYSGG crystals and sensitizer/deactivator-doped Er:GYSGG crystals are not as fully investigated as Nd:GYSGG, although some feedback on the crystal growth and main spectral properties (absorption and emission spectra, energy transfer diagram, etc.) is available in several works published in the past few years [8][9][10][11]. Photographs of as-grown Nd 3+ -and Er 3+ -doped GYSGG crystals: (a) Nd:GYSGG [5]; (b) Er:GYSGG [8]; (c) Er,Pr:GYSGG [9]; (d) Cr,Er,Pr:GYSGG [10].…”

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 4 I 11/2 ? 4 I 13/2 transition of Er 3+ is an effective and mature approach to obtain around 2.9 lm laser [5][6][7]. Another possibility of generating 2.9 lm radiation is the 5 I 6 ?…”

“…Therefore, 2.911 lm lasers can transmit through the ground of containing water vapor because of the low water absorption loss, which have important applications in the fields of the detection, military, and scientific research. Some literature have reported [4][5][6][7] that Er 3+ doped laser crystals could generate 2.7-3.0 lm lasers with the level transition from 4 I 11/2 to 4 I 13/2 . The Ho 3+ ions have also been investigated to realize 2.8-3.1 lm lasers with the 5 I 6 ?…”
