摘要

The growth of undoped BaLiF_3 (BLF) single crystals, a candidate for window material in the vacuum-ultraviolet (VUV) region, was carried out in a Czochralski system under CF_4 atmosphere. BLF single crystals 1 inch in diameter were obtained and characterized. The thermal expansion coefficient of the BLF single crystal along the <100>-axis was 3.33 X 10~(-5) K. The distribution of birefringence along the <100>-axis was in the order of 10~(-7). The absorption edge of BLF was determined to be 123 nm, showing high potential as an optical window material in the VUV region.
