Abstract

High optical quality La~3~Ga~5~SiO~14~ (abbreviated as LGS):Tm single crystals with dopant concentrations of 1 at% Tm^3+^ ions were grown by the Czochralski method. The absorption spectrum and fluorescence spectrum of LGS:Tm crystals were measured at room temperature. Based on Judd–Ofelt method, the spectroscopic parameters were obtained, such as intensity parameters Ξ©~t~ (t = 2, 4, 6), the experimental and theoretical oscillator strength, spontaneous emission probabilities, the radiative lifetime, and the fluorescence branching ratios. The calculated results showed that LGS:Tm is a potential solid‐state laser crystal and has probably realized the 1721 nm and 786 nm laser emission. (Β© 2007 WILEY‐VCH Verlag GmbH & Co.

Single crystals of Holmium (Ho) doped La 3 Ga 5 SiO 14 were grown along c-axis by using the Czochralski method. The structure of the crystal was studied by X-ray powder diffraction (XRPD) and found the crystal structure still belonged to the space group P321. The unitcell parameters were calculated
