Abstract

Laser-based spectroscopy and spectrometry were extensively investigated in nanoscience, materials science, biomedical science, and others. 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 our research was to improve the sensitivity, spectral resolution, and spatial resolution of different laser-based spectroscopy and spectrometry techniques, such as tip- and surface-enhanced Raman spectroscopy (TERS and SERS), coherent anti-Stokes Raman spectroscopy (CARS), optical emission spectroscopy (OES), laser-induced breakdown spectroscopy (LIBS), and laser-assisted mass spectrometry (LAMS).
