“…In addition to being a common impurity in these new oxygen ion-conducting materials, LSG has attracted much recent attention as an important optical material; it has potential as a solid state laser (Rybaromanowski et al, 1996;Malinowski et al, 1996;Simondi-Teisseire et al, 1997;Burshtein et al, 1997) and doping with Nd, Pr, Eu, Er and Yb can be used to tune the operation wavelength (Rybaromanowski et al, 1996(Rybaromanowski et al, , 1997Malinowski et al, 1996;Simondi-Teisseire et al, 1997). Refractive index studies indicate that LSG and its derivatives could be used for a number of nonlinear optical applications (Burshtein et al, 1996). The structures of these materials are thus of much importance in understanding the optical properties.…”

Phases of general formula (RE,A) 2 M 3 O 7 (RE=lanthanide, A=Ca, Sr, Ba; M=Ga, Al) are of interest for their nonlinear optical properties and have potential as solid state lasers. Their structures have been refined using X-ray and neutron diffraction data and are related to gehlenite, Ca 2 Al 2 SiO 7 , with M cations occupying Al and Si sites and RE and A cations sharing the Ca site with no evidence for ordering, although they occur in the ratio 1:1 because of stoichiometry; the M cations are tetrahedrally coordinated. (RE,Ba) 2 M 3 O 7 compounds cannot be synthesized for M=A1 or for RE cations smaller than Sm; this limitation is believed to be due to size mismatch between cations within the structure. © 1999 International Centre for Diffraction Data.

“…The earliest crystal growth of SLGO might have begun in 1992 by Polish scientist Ryba-Romanowski et al It is an excellent laser gain media, and up until now, many kinds of rare earth ions were doped into this crystal and studied systematically, such as Nd 3+ , − Pr 3+ , Dy 3+ , Ho 3+ , etc. ; − a Co 2+ -doped SLGO crystal was studied with focus on the Jahn–Teller effect. , The studies on the nonlinear refractive indices and the radiation defects of SLGO crystal were carried out. − The crystal-field analysis for Nd 3+ ions in SLGO crystal was demonstrated . The whole-view research on the analyses of broad band, near-infrared emission in ABCO 4 and ABC 3 O 7 crystals was presented by the earliest researcher of this crystal (Witold Ryba-Romanowski) in 1997 .…”

High-quality bulk single crystals of pure and Er 3+ -doped SrLaGa 3 O 7 (SLGO) were grown successfully by the Czochralski method. The crystal structure of SLGO was demonstrated. The theoretical calculations based on density functional theory methods were carried out on the SLGO crystal. Its band structure and density of state were presented. The absorption, up-conversion, near-infrared and mid-infrared fluorescence spectra, as well as the fluorescence decay curves of Er: 4 I 13/2 and 4 I 11/2 levels of the Er:SLGO crystal were measured at room temperature. The spectroscopic properties including the absorption and emission cross sections as well as the fluorescence lifetimes were revealed. It is concluded that the Er:SLGO crystal is a promising candidate material for achievement of a mid-infrared laser.

“…Several members of rare-earth (Yb 3 , Nd 3 , Er 3 )-doped M 3 Re 2 BO 3 4 (M Ca, Sr, Ba; Re Y, La, Gd) were investigated earlier [5][6][7][8][9][10][11], and the corresponding growth experiments showed that large-sized rare-earth-doped M 3 Re 2 BO 3 4 laser crystals can be grown well by using the Czochralski method, and the absorption and emission spectra are strongly inhomogeneously broadened due to the disordered lattice. The broad spectrum features a very efficient pumping and the production of ultrashort pulses [12,13].…”

Detailed polarized spectral properties of a 0.685 at. % Nd(3+):Sr(3)Y(2)(BO(3))(4) crystal grown by the Czochralski method have been investigated, including the absorption cross section, the emission cross section, and the fluorescence lifetime. The anisotropy of the spectral properties in different polarized directions was discussed thoroughly. The absorption and emission spectra of Nd(3+) are found to be inhomogeneously broadened due to its internal disordered lattice. Additionally, the CW laser operation at 1.06 μm was also demonstrated for the first time. The maximum output power of 905 mW was achieved, with corresponding optical conversion efficiency of 10.8% and slope efficiency of 12.8%.
