Chau Truong presented her poster on single-shot waveform measurements in the near-infrared at the 2022 CREOL Industrial Affiliates Day! Nice job, Chau!

Our paper was highlighted in an article on UCF Today! Thanks to Zenaida and team for the nice article! https://www.ucf.edu/news/ucf-develops-the-worlds-first-optical-oscilloscope/

Our article “Sing-shot measurement of few-cycle laser waveforms” was published in Nature Photonics! This work was led by postdoc Yangyang Liu. A read-only version of the article can be found here. Congratulations to the whole team!

Our article “Thermal effects in molecular gas-filled hollow-core fibers” was published online in Optics Letters (https://doi.org/10.1364/OL.422983)! This work was led primarily by John Beetar, and features some cool measurements showing how the supercontinuum spectrum generated in N₂O-filled fiber varies from shot to shot at 50 kHz repetition rate as it approaches thermal equilibrium.

Jonathan Nesper was awarded the 2021 Department of Defense National Defense Science and Engineering Graduate Fellowship! For the next three years, Jonathan will be supported by the fellowship to develop intense, long-wavelength sources for coherent control of magnetism in antiferromagnetic insulators. Congratulations, Jonathan!

Our article “All-optical sampling of few-cycle infrared pulses using tunneling in a solid” was published online in Photonics Research (doi: https://doi.org/10.1364/PRJ.420916, Early Posting pdf: https://www.osapublishing.org/prj/upcoming_pdf.cfm?id=420916)! This work was led primarily by Yangyang Liu, but with important contributions from current and former members of the LUMAS group. The work describes a variant on the TIPTOE (tunnel ionization with a perturbation for time-domain observation of an electric field) technique for characterizing laser waveforms, and we are excited about its future prospects for single-shot, on-chip waveform measurements!

John and Mike co-authored a Nature News & Views article, “Spectral narrowing broadens applications” describing the recent work “Extreme-ultraviolet spectral compression by four-wave mixing” by Drescher and colleagues from the Max-Born Institute in Berlin. It’s always a pleasure to be able to help spotlight important work like this!

John completed his PhD yesterday, with the successful defense of his dissertation entitled “Tunable Few- To Many-Cycle Source for High-Order Harmonic Generation and Time-Resolved Spectroscopy” on Zoom. Congratulations to Dr. Beetar!

Last Friday, we welcomed UCF President Alexander Cartwright to the LUMAS lab! Here, PhD student John Beetar explains how control over light fields can allow us to control quantum material properties and allow us to transition fundamental science of strong-field interactions into novel devices!

Our recent work is highlighted in the November 2020 issue of Optics and Photonics News! The article “Towards Attosecond Science with Workaday Lasers” covers work published in our recent Science Advances paper.
