Growth of large CsB3O5 crystals

Mechanical properties of single crystalline and glassy lithium triborate

“…For the (001) crystal plane, the nanohardness (H Meyer ~14.3 -15.0 GPa at 0.5 mN and H Meyer ~9.5 -10.9 at 16 mN) was found to be lower than for the (010) and (100) planes at almost all of the loads. This tendency differs from microhardness results presented by [50]. They report Vickers hardness is highest for (001) plane (7.4 -8.1 GPa) in comparison to 4.7 -5.6 GPa for (100) and 4.4 -5.3 GPa for (010) atomic planes.…”

Growth and characterization of nonlinear optical crystal BaCaBO3F

“…They are widely used in various nonlinear optical devices, for instance, based on frequency conversion and optical parametric oscillation, as well as in electro-optic modulation devices, which are applied in full-color laser displays, high-resolution laser printing, color projection, high-density optical data storage, underwater communications, stereo lithography and other fields. The extensive search for new types of borate NLO crystals has led to the discovery of many excellent materials, such as CsB 3 O 5 (CBO) [3], CsLiB 6 O 10 (CLBO) [4], Sr 2 B 2 Be 2 O 7 (SBBO) [5], K 2 Al 2 B 2 O 7 (KABO) [6], etc. Since fluoride single crystals usually have a wide range of transparency, some fluoroborate crystals, such as KBe 2-BO 3 F 2 (KBBF) [7] and BaAlBO 3 F 2 (BABF) [8], have been studied in recent years.…”

Czochralski and Flux Growth of Crystals for Lasers and Nonlinear Optics

“…However, since Cs 2 O is more volatile than B 2 O 3 , especially in the case of large-temperature gradients (60 C/cm in the vertical direction) for the CZ method, the former melt composition deviates from the stoichiometry of CBO. At the same time, a 65 Â 44 Â 49 mm 3 CBO single crystal was grown from a 3-5 mol.％ Cs 2 O-enriched melt by means of the ISSG method [147]. These problems lead to unstable growth (spontaneous nucleation, inclusions, hopper growth, etc.…”
