中文摘要	Neodymium-doped strontium lanthanum magnesium aluminoxide (Sr1-xLax-yNdyMgxAl12-xO19, Nd:ASL) single crystals were grown by the Czochralski technique. Branching ratios for both transitions 4F3=2!4I9=2 (900 nm) and 4F3=2!4I11=2 (1053 nm) were calculated to be 45% by the Judd–Ofelt theory based on polarized absorption spectra of Nd3C. The spectroscopic quality factors (X D 4= 6) of X D 0:87 for polarization and X D 1:55 for polarization were calculated for 7 at.% Nd:ASL crystal. Quantum efficiency was calculated to be 74%. Laser operation was pumped by a 792 nm LD source. By adopting 7 at.% Nd:ASL crystal as gain media, output power of 5.7 W and slope efficiency of 50% were obtained at 1053 nm with output coupler T D 9:79% and achromatic lens focus of 75 and 150 mm. Output power of 6.9 W and slope efficiency of 36% at 1053 nm, together with output power of 1.72 W and slope efficiency of 17% at 900 nm were obtained in 5 at.% Nd:ASL crystal.
