Abstract

A new laser crystal Pb~3~Ga~2~Ge~4~O~14~:Nd^3+^ with disordered trigonal structure was developed. Its roomโ€temperature stimuโ€ lated emission at โ‰ˆ1.075 ยตm wavelength (^4^F~3/2~ โ†’ ^4^I~11/2~ lasing channel) with laserโ€diode pumping was excited. (ยฉ 2005 WILEYโ€VCH Verlag GmbH & Co.

Bridgman growth of Nd:SGG (Sr 3 Ga 2 Ge 4 O 14 ) crystals has been investigated for the first time. Pt crucible of ร˜25mmร—250mm with a seed well of ร˜10mmร—80 mm is used, and seed is SGG crystal of ร˜10mmร—50mm grown by Bridgman method in advance. The growth parameters are optimized as the furnace temper
