Mechanisms of multiphoton photoemission from metal surfaces

Abstract

Multiphoton photoemission (MPP) from metal surfaces with energy, momentum, time, and resolution enables probing the electronic structure, optical response, and electron dynamics at metal surfaces. We discuss recent progress in understanding of the MPP excitation process for Ag(111) and Cu(111) surfaces using tunable femtosecond laser excitation and photoelectron E(k) imaging.
