  "abstract": "2 at.% Yb:(LuxY1-x)(3)Al5O12(x = 0, 0.25, 0.5, 0.75, 1) garnet crystal rods were successfully grown using the micro-pulling-down (mu-PD) method. The effect of different ratios of Lu(3+)and Y(3+)ions on the crystal structure and the luminescence of Yb(3+)ions in (LuxY1-x)(3)Al(5)O(12)crystals was systematically studied. Optical microscopy revealed a clear composition-dependent increase in crystal defects with increasing Lu(3+)content. Yb:YAG exhibited the highest optical quality, containing only a few small spherical bubbles (<10 & micro;m) and a thin bubble-rich peripheral layer (similar to 10 & micro;m). In contrast, Yb:LuAG showed larger and more elongated bubbles (10-30 & micro;m), thicker bubble-rich regions (150-200 & micro;m), and frequent crack-like defects. Bubble elongation along the growth direction was also observed. The absorption spectra show that with the increasing of Lu(3+)concentration, the main absorption peak gradually blue shifts, and the absorption cross-section gradually decreases. As the Lu(3+)content increases, the emission cross-section of the crystal at 1030 nm increases from 2.27 & times; 10(-20)cm(2)to 2.61 & times; 10(-20)cm(2). The fluorescence lifetime of the Yb:LuYAG crystal falls between those of Yb:YAG and Yb:LuAG crystals. These results demonstrate that the optical properties of Yb:LuYAG crystals strike a balance between the characteristics of YAG and LuAG, providing more options for near-infrared laser applications.",
