No, we didn’t attend a meeting about flying saucers! The Barty Group presented five posters and one talk at Ultrafast Optics XIII (UFO XIII), held this year in San Carlos de Bariloche, Argentina at the Llao Llao Hotel. This post’s image is the gorgeous view from the Llao Llao hotel. Ultrafast Optics is a conference that invites scientists from across the globe to present on the latest developments in ultrafast (few picosecond or shorter) pulses of light and their applications. The conference is held every other year, each time in a unique location.
Kyle Chesnut gave the talk “Spatially and Temporally Chirped Beams: The Single Aperture Path to Exawatt Peak-Power Lasers,” discussing a path to exawatt scale lasers via chirped pulse juxtaposed with beam amplification (CPJBA). Kyle also authored the poster “Amplitude Neutral Temporal Electric-field Autocorrelator with Exquisite Resolution (ANTEATER)“, which was co-authored and presented by Haytham Effarah. This poster presented a novel amplitude balanced and dispersion compensated interferometric autocorrelator, used to measure the durations of ultrafast light pulses, that was designed and built in the Barty Lab.
Trevor Reutershan presented the poster “Path to 100 fs multi-MeV gamma rays from extremely brilliant Compton sources,” which is about how Extremely Brilliant Compton Scattering can be used to generate sub-100 fs, MeV scale pulses of light. Michael Seggebruch presented the posters “Shorter Duration Ultrafast Electro-optic Frequency Combs via Multi-Wavelength Seeding” and “Synthesis of Multi-GHz Ultrafast Pulse Trains via Harmonic Bandwidth Broadening of Electro-Optic Frequency Combs,” both of which present methods for generating shorter duration pulses from Multi-GHz electro-optic frequency combs. Eric Nelson presented the poster “Space-Time Correlated Foci of Exotic Spatially Chirped Femtosecond Beams,” which discusses the foci of exotic spatially chirped beams and their practical implementations.
