Laser-produced plasmas effectively convert high energy laser pulses into incoherent light in the XUV and are suitable pumping sources for high energy transitions. An experimental apparatus was constructed appropriate for preliminary studies in both barium and helium. For barium, dye laser excitation of an appropriate target state was explored as an initial step towards efficient pumping of core-excited states of the barium ion. In helium, studies explored methods to reduce the resonant trapping of the He(II) ion which limits the ability to produce an inversion on the n = 4 $\to$ 2 transition and the n = 3 $\to$ 2 transition. 124 p. application/pdf eng ElectronicsElectrical engineeringAtomic physics Inner-shell excitation of atoms for the development of short wavelength laser sources Thesis Text Physics Natural Sciences Rice University Masters Master of Science Petersen, Timothy Wayne.
