Exploration of the crystal growth, spectroscopy, and LD-pumped 2.7 μm laser operation of Er:LuScO3 sesquioxide crystals

Design, Growth, and Characterization of High Verdet Constant Magneto-Optical Crystal in Cubic Oxide System Tb2O3/Y2O3/ZrO2 Crystal with Enhanced Laser-Induced Damage Threshold

“…They have total of 32 cationic positions in the unit cell, which are divided into two rare-earth sites: the local noncentrosymmetric C 2 (3/4) (Figure 1d) and centrosymmetric C 3i (1/4) sites (Figure 1e). 42 Zr 4+ ions will co-occupy both cationic sites with Y 3+ and Tb 3+ ions to maintain a stable solid solution system when they are embedded into the lattice. Each cation (Tb 3+ /Y 3+ /Zr 4+ ) of the TYZ-1 crystal is surrounded by an octahedron composed of O 2− ions, with a coordination number of six.…”

“…The TYZ-1 crystal grains are determined using structure refinement to have a space group of Ia (Figure c). They have total of 32 cationic positions in the unit cell, which are divided into two rare-earth sites: the local noncentrosymmetric C 2 (3/4) (Figure d) and centrosymmetric C 3i (1/4) sites (Figure e) . Zr 4+ ions will co-occupy both cationic sites with Y 3+ and Tb 3+ ions to maintain a stable solid solution system when they are embedded into the lattice.…”
