Second harmonic generation of spatiotemporal optical vortices and conservation of orbital angular momentum
S. W. Hancock, S. Zahedpour, H. M. Milchberg
Spatiotemporal optical vortices (STOVs) are a new type of intrinsic optical orbital angular momentum (OAM) structure in which the OAM vector is orthogonal to the propagation direct…
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…
Self-waveguiding of relativistic laser pulses in neutral gas channel
L. Feder, B. Miao, J. E. Shrock +2
We demonstrate that an ultrashort high intensity laser pulse can propagate for hundreds of Rayleigh ranges in a prepared neutral hydrogen channel by generating its own plasma waveg…
Guiding of high-intensity laser pulses in 100mm-long hydrodynamic optical-field-ionized plasma channels
A. Picksley, A. Alejo, J. Cowley +11
Hydrodynamic optically-field-ionized (HOFI) plasma channels up to 100mm long are investigated. Optical guiding is demonstrated of laser pulses with a peak input intensity of $6\tim…
Full path single-shot imaging of femtosecond pulse collapse in air turbulence
I. Larkin, J. Griff-McMahon, A. Schweinsberg +3
In a single shot, we measure the full propagation path, including the evolution to pulse collapse, of a high power femtosecond laser pulse propagating in air. This technique enable…
Absolute measurement of laser ionization yield in atmospheric pressure range gases over 14 decades
D. Woodbury, R. M. Schwartz, E. Rockafellow +2
Strong-field ionization is central to intense laser-matter interactions. However, standard ionization measurements have been limited to extremely low density gas samples, ignoring…
