High Repetition-Rate Ultrafast VUV Light Source Development for Attosecond Dynamics at Surfaces

Abstract

Many experiments in attosecond science are limited by the available vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) photon flux and pulse repetition rate. We propose to develop a high repetition rate (100 MHz) source of isolated attosecond pulses (IAP) in the VUV. High-order harmonics in solids will be driven by a high-power optical parametric amplifier (OPA) recently constructed in the Allison lab at Stony Brook University. First experiments using one color from the OPA will focus on mascropic aspects of solid-state HHG critical for source development, such as sample damage at 100 MHz repetition rate, carrier relaxation in wide bandgap insulators, and absolute HHG yields. Subsequent single-pass HHG experiments will use multiple colors from the OPA to study the attosecond dynamics of solid-state HHG and multi-color gating schemes for generating IAPs. Temporal characterization of the generated pulses will be explored using a combination of optical wavemixing and time-resolved photoelectron spectroscopy from surface plasmon polaritons excited in thin metalic films.
