项目摘要

The goal of this work is to prepare solid-state inorganic oxides, phosphate fluorides, and fluorides that may find use as optical frequency converters and laser crystals. Preparative work with frequency converters involves the develpment of crystal chemistry of selected borates. The understanding of these materials are advanced with the computation of microscopic hyperpolarizabilities (beta) from macroscopic d coefficients and continuing applications of the anionic group theory. Work with laser hosts focuses on the development of materials in the STACK family and synthesis of new phosphate fluorides and fluorides. The synthesis of these materials should provide a variety of new crystals for study in diode-pumped or high cross-section, high-power laser systems. %%% The objective of this work is to synthesize and study new solid- state ceramics that may be used as laser crystals or optical second-harmonic generators. Simple concepts in reaction and crystal chemistry are implemented in designing or selecting new materials that have suitable optical characteristics and can be grown as large single crystals. Optical studies of these materials provides the basis for testing and developing the applicability of the concepts and materials themselves. The realization of materials having superior characteristics may well afford new sources of high-power laser light for applications ranging from industrial manufacturing to the generation of x-rays for living- cell holography.

这项工作的目的是准备固态无机氧化物，磷酸盐氟化物和氟化物，这些氧化物可能会发现用作光频转换器和激光晶体。使用频率转换器的制备工作涉及选定硼酸盐晶体化学的开发。通过从宏观D系数和阴离子组理论的持续应用中计算微观超极化（beta）的计算，对这些材料的理解是提出的。与激光宿主的合作重点是堆栈家族中材料的发展以及新的磷酸盐氟化物和氟化物的合成。这些材料的合成应提供多种新晶体，以研究二极管或高横截面高功率激光系统的研究。 %%％这项工作的目的是合成和研究可用作激光晶体或光学第二谐波发电机的新的固态陶瓷。在设计或选择具有合适光学特性的新材料时，可以将反应和晶体化学的简单概念作为大型单晶生长。这些材料的光学研究为测试和开发概念和材料本身的适用性提供了基础。具有较高特性的材料的实现很可能为从工业制造到生物全息X射线的应用提供了新的高功率激光光的新来源。
