Laser-Based Spectroscopy And Spectrometry, Xiangnan He

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Laser-based spectroscopy and spectrometry were extensively investigated in nanoscience, materials science, biomedical science, and etc. Different lasers with wavelengths from ultraviolet to infrared, and with duration from continuous-wave (CW) to femtoseconds have been employed in various spectroscopic techniques to investigate the properties of materials and nanostructures. However, the sensitivity, spectral resolution, and spatial resolution of these techniques still need to be improved to better serve the purposes of detecting and analyzing various materials. The objective of the research in this dissertation is to improve the sensitivity, spectral resolution, and spatial resolution of different laser-based spectroscopy and spectrometry techniques, such as …
