Key words：Cz method; Nd: GGG; spectral properties; rare earths;
Abstract: The laser crystal Nd: GGG was grown by Cz method. The optimum processing parameter is that the pulling rate is 2~4mm·h-1, the rotation rate is 20~40 r·min-1 and the cooling rate is 20℃. The absorption and fluorescence spectra of Nd: GGG were measured. The main absorption peak of Nd: GGG is at 808 nm and the fluorescence emission peak is at 9430cm-1, corresponding to 4F3/2-4I11/2 emission band of Nd3+ ions.
