| Abstract: | We report on the top-seeded solution growth of LiB3O5 from an excess B2O3 solution. Parameters investigated include the Li2O/B2O3 ratio, rotation rate, pulling rate, cooling rate, and seed direction. With careful control of the above parameters, we have grown clear crystals of 25 × 30 × 20 mm in size. Selected nonlinear optical properties of these crystals are reported. Observations concerning the occurrence of unstable growth (inclusions, hopper growth) are discussed, and methods to eliminate the unstable growth are suggested. |
