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…
Extreme Ultraviolet Time- and Angle-Resolved Photoemission Spectroscopy with 21.5 meV Resolution using High-Order Harmonic Generation from a Turn-Key Yb:KGW Amplifier
Yangyang Liu, John E. Beetar, Md Mofazzel Hosen +11
Characterizing and controlling electronic properties of quantum materials require direct measurements of non-equilibrium electronic band structures over large regions of momentum s…
Dramatic enhancement of supercontinuum generation in elliptically-polarized laser filaments
Shermineh Rostami, Michael Chini, Khan Lim +6
Broadband laser sources based on supercontinuum generation by femtosecond laser filamentation have enabled applications from stand-off sensing and spectroscopy to the generation an…
