Diagnostic Techniques for Particle-in-Cell Simulations of Laser-produced Gamma-rays in the Strong-field QED Regime
A. H. Younis, A. Davidson, B. Hafizi +1
The emission of multi-MeV (-ray) photons from the interaction of a high-powered laser pulse with a dense plasma target is studied using particle-in-cell simulations. A new set o…
Special unitary particle pusher for extreme fields
Daniel Gordon, Bahman Hafizi
An exact momentum update useful for particle codes was previously given. The expressions involved were unwieldy. By treating the momentum as a representation of SU(2)xSU(2) instead…
Backward Raman Amplification in the Long-wavelength Infrared
L. A. Johnson, D. F. Gordon, J. P. Palastro +1
The wealth of work in backward Raman amplification in plasma has focused on the extreme intensity limit, however backward Raman amplification may also provide an effective and prac…
Two-photon vibrational excitation of air by long-wave infrared laser pulses
J. P. Palastro, J. Penano, L. A. Johnson +3
Ultrashort long-wave infrared (LWIR) laser pulses can resonantly excite vibrations in N2 and O2 through a two-photon transition. The absorptive, vibrational component of the ultraf…
Gigavolt bound-free transitions driven by extreme light
Daniel F. Gordon, John P. Palastro, Bahman Hafizi
The photoelectron spectrum in the ultra-relativistic limit of tunneling ionization is strongly affected by wave-particle resonance and finite spot-size effects, in contradistinctio…
Stimulated Raman Scattering and Nonlinear Focusing of High-Power Laser Beams Propagating in Water
B. Hafizi, J. P. Palastro, J. R. Penano +4
The physical processes associated with propagation of a high-power (power > critical power for self-focusing) laser beam in water include nonlinear focusing, stimulated Raman scatt…
