In this paper we report the growth and characterization of Nd:(Lu x Gd 1Àx ) 3 Ga 5 O 12 crystal for the first time. The polycrystalline materials were synthesized by conventional solid-state reaction. Single crystal with good optical quality was successfully obtained and the dimensions of the as-grown crystal were Ø21 Â 30 mm 3 . X-ray powder diffraction studies confirm that the Nd:(Lu x Gd 1Àx ) 3 Ga 5 O 12 crystal is isostructural with Gd 3 Ga 5 O 12 with unit cell parameter of 1.2361 nm which is less than that of Gd 3 Ga 5 O 12 crystal (1.2376 nm). The absorption and emission spectra of the crystal at room temperature have also been studied. Continuous-wave (CW) laser performance at 1.06 lm has been demonstrated on the crystal.
