Propagation of Bessel and Airy beams through atmospheric turbulence
W. Nelson, J. P. Palastro, C. C. Davis +1
We investigate, through simulation, the modifications to Bessel and Airy beams during propagation through atmospheric turbulence. We find that atmospheric turbulence disrupts the q…
Model for the Atomic Dielectric Response in Time Dependent Laser Fields
T. C. Rensink, T. M. Antonsen, J. P. Palastro +1
A nonlocal quantum model is presented for calculating the atomic dielectric response to a strong laser electric field. By replacing the Coulomb potential with a nonlocal potential…
Quasi-phasematched laser wakefield acceleration
S. J. Yoon, J. P. Palastro, H. M. Milchberg
The energy gain in laser wakefield acceleration (LWFA) is ultimately limited by dephasing, occurring when accelerated electrons outrun the accelerating phase of the wakefield. We a…
Time-dependent polarization states of high power, ultrashort laser pulses during atmospheric propagation
J. P. Palastro
We investigate, through simulation, the evolution of polarization states during atmospheric propagation of high power, ultrashort laser pulses. A delayed rotational response model…
THz generation by optical Cherenkov emission from ionizing two-color laser pulses
Luke A. Johnson, John P. Palastro, Thomas M. Antonsen +1
Two-color photoionization produces a cycle-averaged current driving broadband, conically emitted THz radiation. We investigate, through simulation, the processes determining the an…
Pulsed Mid-infrared Radiation from Spectral Broadening in Laser Wakefield Simulations
W. Zhu, J. P. Palastro, T. M. Antonsen
Spectral red-shifting of high power laser pulses propagating through underdense plasma can be a source of ultrashort mid-infrared (MIR) radiation. During propagation, a high power…
Effect of two-beam coupling in strong-field optical pump-probe experiments
J. K. Wahlstrand, J. H. Odhner, E. T. McCole +4
Nonlinear optics experiments measuring phase shifts induced in a weak probe pulse by a strong pump pulse must account for coherent effects that only occur when the pump and probe p…
