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

采用Kyropolous生长方法制备了SrBrO7 （SBO）单晶，采用不同的生长参数，包括前驱体纯度和生长速率。随后使用光学显微镜、真空紫外（VUV）透射光谱和x射线衍射光谱等分析技术对生长晶体进行了表征。激光诱导损伤的研究也通过单次和多次辐照进行。采用Kyropolous生长方法成功制备了高质量的b轴取向SBO单晶，尺寸为100毫米（大），VUV透过率高达80%，并具有高的深紫外（DUV）激光诱导损伤抗力。这些结果已经提交发表，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.
