High-Resolution Spectroscopy and Dynamics of Multiphoton Processes in Atoms and Molecules.
Abstract
This report summarizes research to establish the high-resolution spectroscopy and detailed mechanisms of sequences of resonant transitions induced in atoms and molecules by multicolor, multiphoton excitation. These processes are studied as a function of the independently tunable frequencies and polarization states of multiple dye laser beams in order to establish both the underlying physics and the high degree of selectivity of this advanced form of laser excitation. Detection methods include photoelectron analysis, mass spectrometry, and laser-induced fluorescence. The initial phase of work covered in this report included design, construction, and testing of all major components of the experimental apparatus needed to perform these studies. In addition, measurements of photoelectrons ejected from rare gas atoms by nonresonant, multiphoton excitation are described. (Author)
