ABSTRACT: Gamma-ray spectroscopy has a wide range of applications, including monitoring radioactive waste from mining and oil and gas extraction, nuclear safeguards, industrial process control, and medical imaging. Although high-purity germanium spectrometers have served the field well, their cryogenic cooling requirements can make them difficult to use in the field or in settings where power…

Abstract: Optics damage is a ubiquitous challenge for high-power lasers and largely dictates the size and cost of these facilities. Here, we are developing a new technology that uses gas as an optical medium instead of solids. Our method imprints density modulations as holograms in a gas, achieved via absorption of a spatially modulated “writing…
