Mode structure and orbital angular momentum of spatiotemporal optical vortex (STOV) pulses
S. W. Hancock, S. Zahedpour, H. M. Milchberg
We identify a class of modal solutions for spatio-temporal optical vortex (STOV) electromagnetic pulses propagating in dispersive media with orbital angular momentum (OAM) orthogon…
Transient-grating single-shot supercontinuum spectral interferometry (TG-SSSI)
S. W. Hancock, S. Zahedpour, H. M. Milchberg
We present a technique for the single-shot measurement of the space- and time-resolved spatiotemporal amplitude and phase of an ultrashort laser pulse. The method, transient-gratin…
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…
Bound electron nonlinearity beyond the ionization threshold
J. K. Wahlstrand, S. Zahedpour, A. Bahl +2
Although high field laser-induced ionization is a fundamental process underlying many applications, there have been no absolute measurements of the nonlinear polarizability of atom…
p-Norm Flow Optimization in a Network
Sina Zahedpour, Mehdi Kalantari
In this paper we study information flow paths in a data network, where traffic generated by servers (or sources) takes a multi-hop path in order to reach its clients (destinations)…
