High-order harmonic generation occurs when an intense laser pulse drives an electron away from its parent atom or molecule, before changing direction and accelerating the electron back towards the parent ion. In the ensuing collision, extreme ultraviolet and soft x-ray radiation is emitted. Because of its coherence and extremely short duration, this radiation is useful for studying the world of the ultrafast (around 10-18 s) microscopic world of electronic motion that underpins life, as well as modern technology. Introduction to high-order harmonic generation. This page</a> provides an introduction to the physics of high-order harmonic generation.

My research in the field of high-order harmonic generation includes:
