Different Rise Times of Atomic Br M 3d Core Level Absorptions during Br C State Dissociation via Extreme Ultraviolet Transient Absorption Spectroscopy
John E. Beetar, Jen-Hao Ou, Yuki Kobayashi +1
The reported ''dissociation times'' for the Br C ( ) state by various measurement methods differ widely across the literature (30 to 340 fs). We consider th…
Attosecond Probing of Coherent Vibrational Dynamics in CBr
Jen-Hao Ou, Diptarka Hait, Patrick Rupprecht +3
A coherent vibrational wavepacket is launched and manipulated in the symmetric stretch (a) mode of CBr, by impulsive stimulated Raman scattering from non-resonant 400 nm la…
Ultrafast relaxation of acoustic and optical phonons in a topological nodal-line semimetal ZrSiS
Yangyang Liu, Gyanendra Dhakal, Anup Pradhan Sakhya +7
Despite being the most studied nodal line semimetal, a clear understanding of the transient state relaxation dynamics and the underlying mechanism in ZrSiS is lacking. Using time a…
Single-shot measurement of few-cycle optical waveforms on a chip
Yangyang Liu, John E. Beetar, Jonathan Nesper +2
The measurement of transient optical fields has proven critical to understanding the dynamical mechanisms underlying ultrafast physical and chemical phenomena, and is key to realiz…
Multi-Octave Supercontinuum Generation and Frequency Conversion based on Rotational
John E. Beetar, M. Nrisimhamurty, Tran-Chau Truong +6
The field of attosecond science was first enabled by nonlinear compression of intense laser pulses to a duration below two optical cycles. Twenty years later, creating such short p…
Crystal Symmetry and Polarization of High-order Harmonics in ZnO
Shicheng Jiang, Shima Gholam-Mirzaei, Erin Crites +5
We carried out a joint theoretical and experimental study of the polarization of high-order harmonics generated from ZnO by intense infrared laser pulses. Experimentally we found t…
