Development of Kyropoulos-grown SrB4O7 single crystals as gamma-ray radiation-resistant optical window materials

采用Kyropolous生长法，通过改变前驱体纯度和生长速率，成功地制备了SrBrO_7（SBO）单晶。生长的晶体，随后，其特征在于使用分析技术，如光学显微镜，真空紫外（VUV）透射光谱，和X射线衍射光谱。激光诱导损伤的调查也进行了通过单次和多次照射。采用Kyropolous生长方法成功地制备出了尺寸为100 mm（大）、真空紫外透过率高达80%、抗深紫外激光损伤的高质量b轴取向SBO单晶。这些结果已经提交出版，其中一篇论文最近刚刚被接受，另一篇正在审查中。

SrBrO7 (SBO) single crystals have been successfully fabricated by Kyropolous growth method using different growth parameters including precursor purity and growth rate. The as-grown crystals were subsequently characterized using analytical techniques such as optical microscopy, vacuum ultraviolet (VUV) transmittance spectroscopy, and x-ray diffraction spectroscopy. Laser-induced damage investigations have also been performed through single-shot and multi-shot irradiation. High-quality, b-axis-oriented SBO single crystals with 100-mm dimensions (large), up to 80 % VUV transmittances, and high deep ultraviolet (DUV) laser-induced damage resistance have been successfully prepared by Kyropolous growth method. These results have already been submitted for publication with one paper just recently been accepted and the other under review.
