Abstract
Extreme ultraviolet (EUV) light can be generated through the interaction of a high-intensity laser beam with atoms. When an intense laser pulse hits an atom, its outer electron is pulled away from the atom. The electric field of the laser may then pull the electron back to the atom. When the electron and atom collide, a photon can be emitted.1 As the laser interacts with many atoms near the focus of the beam, the emitted photons build up coherently in the forward direction, creating a highly-directional beam of light. In Dr. Justin Peatross’s lab we work on ways to optimize the generation of these photons, which are high-order harmonics of the original laser beam.
