Two-Photon Detection Techniques for Atomic Fluorine.
Abstract
During the last year, we focused on experiments that will lead to a quantitative and remote diagnostic for atomic fluorine using multiphoton excitation followed by the detection of fluorescence or ionization. Three experimental investigations are summarized in this report. First, we describe an experiment to generate the sixth anti-Strokes (AS) wave at 170 nm from a tunable 285-nm beam for use in a two-photon absorption experiment. Second, we report the first observation of 3+1 resonantly enhanced multiphoton ionization (REMPI) of atomic F at 233 nm and experiments to detect fluorescence from the excited intermediate state. Finally, we describe the development of a time-of-flight (TOF) mass spectrometer to help interpret the combined F2 and F ionization spectra at 286 nm and 233 nm. Keywords: multiphoton ionization spectroscopy, atomic fluorine, fluorine, ionization, spectroscopy.
