Optical Spectroscopy Laboratory for Undergraduates

9451475密苏里大学的钱德拉塞卡将在光学实验室的高年级光与现代光学课程中增加现代光谱学实验。这些设备还将用于现代物理的演示目的和本科生研究。将学习原子、分子和固态光谱。将建立两台现代光谱仪，在室温和低温下进行拉曼和荧光/光致发光研究。将设置分光计，以便可以在最小或没有改变排列的情况下执行这四个实验。此功能在有限时间的实验课中非常重要。一个缺少几个组件的法布里-珀罗三通干涉仪将被完成，并将用于布里渊散射和激光模式研究。将建立一个傅里叶变换光谱仪来研究液体和固体中的振动模式，并将作为拉曼和法布里-珀罗光谱仪的补充工具。所有上述仪器都将由计算机控制。目前，我们的光学实验室缺少上述所有仪器，只能进行手动获取数据的实验，无法进行强度测量和与理论比较。上面的仪器将在课堂上学习的理论和在实验室中所做的实验之间提供更紧密的联系。

9451475 Chandrasekhar The University of Missouri will add modern spectroscopy experiments to the Optics Laboratory for the upper division Light and Modern Optics course. The equipment will also be used for demonstration purposes in Modern Physics and for Undergraduate Research. Atomic Molecular and Solid State Spectra will be studied. Two modern spectrometers will be set up to perform Raman and fluorescence/photoluminescence studies at room and low temperatures. The spectrometers will be set up so that the four experiments can be performed with minimal or no change in the alignment. This feature is critical in a limited time laboratory class. A Fabry Perot triple pass interferometer which lacks a few components will be completed and will be used to perform Brillouin scattering and laser mode studies. A Fourier transform spectrometer will be set up to study the vibrational modes in liquids and solids, and will be a complementary tool to the Raman and Fabry Perot spectrometers. All the above instruments will be computer controlled. At present our Optics laboratory lacks all of the above instruments, and we are able only to perform experiments where data is taken manually, so that intensity measurements and comparison with theory is not possible. The instrumentation above will provide a closer link between the theory studied in class and the experiments done in the lab.
