Abstract

Nd:Sr~3~Ga~2~Ge~4~O~14~ (Nd:SGG) single crystals up to βˆ…οΈ25 mm Γ— 50 mm were grown by the modified Bridgman method. Absorption and fluorescence spectra of Nd:SGG crystals were measured at room temperature. Compared with Nd:YAG crystals, the absorption of Nd:SGG single crystals presented broad absorption bands of Nd^3+^ ions. The fluorescence inten‐ sity increased with Nd concentration while the fluorescence lifetime of the ^4^F~3/2~–^4^I~11/2~ transition excited by a diode laser at room temperature showed a slight decrease when the Nd concentration increased to 8 at%. The results indicated that the quenching effect might occur in Nd:SGG crystals doped with higher Nd concentrations. (Β© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract A new laser crystal Pb~3~Ga~2~Ge~4~O~14~:Nd^3+^ with disordered trigonal structure was developed. Its room‐temperature stimu‐ lated emission at β‰ˆ1.075 Β΅m wavelength (^4^F~3/2~ β†’ ^4^I~11/2~ lasing channel) with laser‐diode pumping was excited. (Β© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, We
