Materials Science and Nonlinear Optics in Physics and Chemistry Laboratories

摩拉维亚学院试图在其物理课程中增加非线性光学的新颖实验；此外，非线性光学材料的制造将为物理和化学课程增加一个重要的材料科学组成部分。最近开发的具有光折变非线性光学特性的聚合物复合材料已经在Moravian学院制造出来；我们的目标是将这些材料的合成纳入有机化学实验室，将其热学和材料性质的研究纳入物理化学实验室，将其非线性光学性质的研究纳入光学实验室。新的光学实验将包括动态衍射光栅的产生和探测，激光束通过光栅传播的耦合研究，非线性光学材料中光学图像的存储和检索，和光折变放大元件光学振荡器的研究。化学课程的学生将合成光学专业学生使用的高分子复合材料，并有机会通过组分的变化了解复合材料的材料和物理性质。有机专业的学生将学习发色团结构与其紫外可见光谱的关系，物理化学专业的学生将研究聚合物基体中组分的相行为。本提案所要求的设备将允许摩拉维亚学院建立一套物理和化学实验，探索非线性光学行为及其与材料特性的关系。

Moravian College seeks to add novel experiments in nonlinear optics to its physics curriculum; in addition, the fabrication of the nonlinear optical materials will add an important material-science component to both the physics and chemistry curricula. Recently developed polymer composites that exhibit photorefractive nonlinear optical properties have been fabricated at Moravian College; our goal is to merge the synthesis of these materials into the organic chemistry lab the study of their thermal and material properties into the physical chemistry lab, and the study of their nonlinear optical properties into the optics lab. Novel experiments in optics will include the generation and probing of dynamic diffraction grating, the study of laser beam coupling via propagation through a grating, the storage and retrieval of optical images in nonlinear optical materials, and the study of optical oscillators with photorefractive amplifying elements. Students in chemistry courses will synthesize the polymer composites used by the optics students and have an opportunity to learn how material and physical properties of the composite are by changes in their components. Organic students will study the relationship of the chromophore structure to its UV-Vis spectrum, and physical chemistry students will examine the phase behavior of the components in the polymer matrix. The equipment requested in this proposal will allow Moravian College to establish a suite of experiments in physics and chemistry that explore nonlinear optical behavior and its relationship to material properties.
