摘要：

The growth of undoped BaLiF3 (BLF) single crystals, a candidate for window material in the vacuum-ultraviolet (VUV) region, was carried out in a Czochralski system under CF4 atmosphere. BLF single crystals I 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. (C) 2002 Elsevier Science B.V. All rights reserved.
