Laser Photoelectron Spectroscopy
Photoemission spectroscopy is an extensively used technique to investigate the electronic characteristics of solid surfaces. In this decade, laser photoemission spectroscopy , in which a laser is used as the excitation light source instead of a helium discharge lamp and/or synchrotron light source, has been developed. Lasers offer many advantages over these conventional light sources, such as strong intensity, coherency, ultranarrow linewidth (or ultrashort pulse duration), and high tunability of polarization.
