Poster: A Computational Study of Extreme Ultraviolet High Harmonic Generation

POSTER

Abstract

Frequency combs are highly coherent light sources that transmit equally spaced, mutually coherent spectral lines, therefore pushing the boundaries of metrology, spectroscopy, and atomic clocks. Specifically, extreme ultraviolet frequency combs are a compelling candidate for precise optical measurements of distance, time, and molecular composition of interstellar fingerprints. High-harmonic generation (HHG) is the most prominent method for generating frequency comb light transfer into the extreme ultraviolet range of the electromagnetic spectrum. We present a design for a HHG light source optimized for precision spectroscopy across a wide wavelength range from 100 to 200 nm. Using a density functional theory framework simulation, we explore HHG in a Xe gas scheme and in promising solid-state materials to determine the best medium for HHG with high power per tooth for precision measurements.
