9625964 Richardson This award provides support for the acquisition of equipment to develop a processing and characterization facility for photo- thermo-refractive glass (PTRG) materials. This facility is critical to the continued progress in the fabrication of new optical recording media for high efficiency volume holographic optical element applications based on glass-ceramic materials. Experimental results obtained at CREOL (Center for Research and Education in Optics and Lasers) during the past 18 months have confirmed for the first time in this country, the potential of an important new technology for recording and storing information through the selective nucleation and crystallization of photo- induced phases in a robust glass matrix. This glass material, however has to date been obtainable only in Russia. As a result of our experiments, the limitations of the Russian material and the importance of processing these materials within our laboratory, has been firmly realized. Establishment of this facility at CREOL will utilize our institute's strengths in both the design and characterization of photorefractive materials and our unique capabilities in the melting and characterization of new glasses for optical applications. CREOL contains one of the few academic research groups in the country specifically engineering and melting new glass compositions for optical applications. This award will enable the establishment of bulk glass processing capabilities and construction of an improved, reliable and accurate holographic element formation and characterization facility. The equipment includes furnace and optical finishing facilities to allow in-house melting and fabrication of glass starting materials, and an ultraviolet (UV) laser system which can efficiently irradiate the glass, forming the hologram, and subsequently characterize the quality of the resulting element. Once operational, irradiation/crystallization studies on in-house produced glass compo sitions, with accompanying analysis of material physical properties thermal, mechanical and optical will continue to be carried out. %%% Establishment of this Processing and Characterization facility will assist in the educational goals of our program at CREOL/UCF. CREOL has been instrumental in establishing Master's and Doctoral degree programs in Optical Sciences and Engineering at UCF. Over twenty courses in optics are taught by twenty five nationally- recognized CREOL faculty. The co-PI's oversee research programs containing a total of 5 students working on various, interdisciplinary topics related to optics. Currently, 2 undergraduate and 2 graduate students utilize limited (nonoxide) glass melting facilities. Acquisition of melting and fabrication equipment identified in this program will allow expansion of lab- based training in traditional glass processing at both graduate and undergraduate levels. A CREOL-funded Ph.D. student will be associated with the glass processing and optical characterization of the PTRG materials. ***

9625964 Richardson 该奖项为购买设备提供支持，以开发光热折射玻璃 (PTRG) 材料的加工和表征设施。 该设施对于基于玻璃陶瓷材料的高效体全息光学元件应用的新型光学记录介质制造的持续进展至关重要。 过去 18 个月在 CREOL（光学和激光研究与教育中心）获得的实验结果首次在该国证实了一项重要新技术的潜力，即通过在坚固的玻璃基体中光致相的选择性成核和结晶来记录和存储信息。 然而，这种玻璃材料迄今为止只能在俄罗斯获得。 通过我们的实验，我们充分认识到俄罗斯材料的局限性以及在我们实验室内处理这些材料的重要性。 在 CREOL 建立该设施将利用我们研究所在光折变材料设计和表征方面的优势，以及我们在光学应用新型玻璃熔化和表征方面的独特能力。 CREOL 是国内为数不多的专门设计和熔化用于光学应用的新型玻璃成分的学术研究小组之一。 该奖项将有助于建立大块玻璃加工能力，并建设改进的、可靠的和准确的全息元件形成和表征设施。 该设备包括熔炉和光学精加工设施，允许内部熔化和制造玻璃原材料，以及紫外线 (UV) 激光系统，该系统可以有效地照射玻璃，形成全息图，并随后表征所得元件的质量。 一旦投入运行，将继续对内部生产的玻璃组合物进行辐照/结晶研究，并对材料物理性能、热学、机械和光学性能进行分析。 %%% 该处理和表征设施的建立将有助于实现我们在 CREOL/UCF 项目的教育目标。 CREOL 在 UCF 光学科学与工程硕士和博士学位课程的建立中发挥了重要作用。 超过 20 门光学课程由 25 名国家认可的 CREOL 教师教授。 联合 PI 负责监督总共 5 名学生的研究项目，研究与光学相关的各种跨学科主题。 目前，2 名本科生和 2 名研究生使用有限的（非氧化物）玻璃熔化设施。 采购该计划中确定的熔化和制造设备将有助于扩大研究生和本科生水平的传统玻璃加工实验室培训。 CREOL 资助的博士学位学生将参与 PTRG 材料的玻璃加工和光学表征。 ***
