Abstract
We report the successful Kyropoulos growth of a large strontium tetraborate (SrB4O7, SBO) single crystal that weighs more than 300 g. In order to grow the large and transparent crystal, a new twin-type stirring blade was used along with a 150 mm diameter crucible. The use of the stirring blade results in the production of the world’s largest SBO crystal with dimensions of 100 mm (a) ×30 mm (b) ×32 mm (c), a weight of 328.2 g, and wide transparency down to 130 nm. These results will then lead to the development of large SBO crystals as optical window materials for high-power DUV laser processing systems.
