Using an incoherent target-return to adaptively focus through atmospheric turbulence
William Nelson, John P. Palastro, Chensheng Wu +1
A laser beam propagating to a remote target through atmospheric turbulence acquires intensity fluctuations. If the target is cooperative and provides a coherent return beam, the ph…
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…
Absolute measurement of the ultrafast nonlinear electronic and rovibrational response in H and D
J. K. Wahlstrand, S. Zahedpour, Y. -H. Cheng +2
The electronic, rotational, and vibrational components of the ultrafast optical nonlinearity in H and D are measured directly and absolutely at intensities up to the ioniza…
Plasma lenses for ultrashort multi-petawatt laser pulses
J. P. Palastro, D. Gordon, B. Hafizi +5
An ideal plasma lens can provide the focusing power of a small f-number, solid-state focusing optic at a fraction of the diameter. An ideal plasma lens, however, relies on a steady…
Accelerated Ions from a Laser Driven Z-pinch
Michael H. Helle, Daniel F. Gordon, Dmitri Kaganovich +3
Intense laser acceleration of ions is inherently difficult due to the velocity mismatch between laser pulses moving at the speed of light and slowly moving massive ions. Instead of…
Dramatic enhancement of supercontinuum generation in elliptically-polarized laser filaments
Shermineh Rostami, Michael Chini, Khan Lim +6
Broadband laser sources based on supercontinuum generation by femtosecond laser filamentation have enabled applications from stand-off sensing and spectroscopy to the generation an…
Enhanced betatron X-rays from axially modulated plasma wakefields
J. P. Palastro, D. Kaganovich, D. Gordon
In the cavitation regime of plasma-based accelerators, a population of high-energy electrons tailing the driver can undergo betatron motion. The motion results in X-ray emission, b…
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…
