High-order Harmonic-generation Using High-power Lasers

Research output: Contribution to journalArticle

Abstract

An introduction to high-power lasers and strong-field laser-atom interactions is given, and the main experimental and theoretical results concerning high-order harmonic generation are reviewed. The single atom response as well as the macroscopic phase-matching effect is discussed. The formation and extent of the characteristic plateau in the harmonic spectra are discussed in terms of a physical picture valid in the tunnel-ionisation regime. Very high-order harmonics have been reported, opening the way to construct bright sources of coherent radiation in the XUV and soft X-ray ranges. Some examples of possible applications of such a source are presented.
