Vacuum-ultraviolet frequency comb spectroscopy apparatus
Abstract
The goal of this proposal is to build an apparatus to perform precision vacuum-ultraviolet (VUV) frequency comb quantum-logic spectroscopy of a wide variety of atomic and molecular ions relevant to department of defense quantum sensing, materials science, and fundamental physics applications. The VUV comb will be based on single-pass high-harmonic generation in a solid-state material or highly-cascaded-harmonic generation in a xenon-filled photonic-crystal fiber of a few-cycle high power Yb-fiber comb to provide broad VUV bandwidth and tunability extending from 140 nm to 280 nm. The VUV light will be used to study many-ion Sn2+ Coulomb crystal clocks, to build thorium nuclear clocks, and to perform spectroscopy of astrophysical ions for fundamental physics tests. This research is critical for US leadership of the quickly developing field of VUV science and engineering, and it will also be used to educate the next generation of scientists and engineers in areas important to national defense.
