Two-Photon-Excited Stimulated Emission from Atomic Hydrogen in Flames

Abstract

Two-photon-excited stimulated emission (SE) has been studied in a variety of atomic and molecular systems for over a decade. However, the effect that SE may have on diagnostic applications of multiphoton-excited fluorescence (FL) detection, and the potential use of SE detection as a useful technique in its own right, have received little attention until a recent report describing SE from atomic oxygen in flames.1 In this summary, we describe two-photon-excited SE and FL measurements of atomic hydrogen in flames.
