Simplified single-shot supercontinuum spectral interferometry
Dhruvit Patel, Dogeun Jang, Scott W. Hancock +2
We have experimentally demonstrated a simplified method for performing single-shot supercontinuum spectral interferometry (SSSI) that does not require pre-characterization of the p…

Free-space propagation of spatio-temporal optical vortices (STOVs)
S. W. Hancock, S. Zahedpour, A. Goffin +1
Spatio-temporal optical vortices (STOVs) are a new type of optical orbital angular momentum (OAM) with optical phase circulation in space-time. In prior work [N. Jhajj et al., Phys…

Ultrashort infrared 2.5-11μm pulses: spatiotemporal profiles and absolute nonlinear response of air constituents
S. Zahedpour, S. W. Hancock, H. M. Milchberg
We measure the detailed spatiotemporal profiles of femtosecond laser pulses in the infrared wavelength range λ=2.5-11μm, and the absolute nonlinear response of major air constituen…
