Two Photon Detection Techniques for Atomic Fluorine

Abstract

This report describes research to develop a sensitive technique for the remote detection of atomic fluorine based on two-photon excitation of high lying atomic states, followed by fluorescence. We report the first demonstration of two-photon excited laser induced fluorescence in F using a pump laser of 180 nm. In addition, we have also observed 3+2 resonantly-enhanced multiphoton ionization (REMPI) of F at 285 nm, and 3+1 REMPI of F at 233 nm. No fluorescence was observed for the three-photon excitation processes. We recommend directions for future research quantify this F-atom detection technique. Keywords: Multiphoton ionization spectroscopy, Atomic fluorine.
