2-Beam Action Spectroscopy for Probing Multiphoton Absorption Processes in Photonic Materials

Not Accessible

Your library or personal account may give you access

Abstract

We employ a new methodology, based on excitation with two independent beams, for determining the order of absorptive nonlinearity and probing multiphoton photophysics in different materials, using polymerization, photocurrent, or fluorescence as proxies for absorption.
