DESCRIPTION (Adapted from applicant's abstract): The goal of this Phase II application is continued development of improved oxide glass infrared transmitting fiberoptics at 2.94 microns for medical applications. In phase I the authors have shown that tensile strength has been improved, the bending diameter decreased and new coatings developed. Substantial progress was made and continuation of the research looks promising. Phase II of the project seeks to improve fiber strength by optimizing glass hardness and drawing the fiber with better coatings. The authors propose to improve fiber transmission by eliminating water from the glass and removing other impurities. Characterization of the optimized fibers will be performed and attempts to draw large amounts of new fiber will be made. PROPOSED COMMERCIAL APPLICATION: NOT AVAILABLE

描述（改编自申请人摘要）：本阶段II的目标 应用是不断发展的改进氧化物玻璃红外 用于医疗应用的2.94微米的传输光纤。一期 作者已经表明，抗拉强度得到了改善，弯曲强度 直径减小并形成新的涂层。取得实质性进展 继续进行这项研究看起来很有希望。项目第二阶段旨在 通过优化玻璃硬度和拉伸纤维来提高纤维强度 更好的涂层。作者建议通过以下方法改善光纤传输： 除去玻璃中的水和其它杂质。 将进行优化纤维的表征，并尝试绘制 将制造大量的新纤维。 拟议商业应用：不可用
