Abstract

Laser-induced plasma multi-charged ion (MCI) sources have gained in popularity over the last thirty years with the advent of reliable, high peak power, short temporal pulse laser systems. Utilization of laser-induced plasma MCI sources allows for production of a wide array of ion species from a variety of source target materials. In this thesis an investigation of the generation of MCis from an aluminum (Al) target source through laser-induced plasma from a femtosecond (fs) pulsed laser system is outlined and the results presented and analyzed. In order to characterize the production of the Al MCis resulting from the fs laser induced plasma five different experiments were devised and conducted. The five experiments are: (1) Al target laser pulse exposure, (2) MCI acceleration by plasma expansion, (3) accelerating bias voltage variation, (4) variance of incident laser pulse fluence, and (5) variance of the Al target surface position axial along the focused laser beam waist. Analysis of the data recorded during execution of each experiment is presented at the end of the respective experimental section. The thesis concludes with an overall summation of the findings of the five experiments as well as proposals for future fs laser-induced Al MCI research.
