Beating Optical Turbulence Limits Using High Peak-Power Lasers
Michael H. Helle, Gregory Dicomo, Samantha Gregory +6
We experimentally demonstrate the ability of a nonlinear self-channeling beam to resist turbulence-induced spreading and scintillation. Spatio-temporal data is presented for an 850…
Nonlinear Frequency Shift in Raman Backscattering and its Implications for Plasma Diagnostics
D. Kaganovich, B. Hafizi, J. P. Palastro +5
Raman backscattered radiation of intense laser pulses in plasma is investigated for a wide range of intensities relevant to laser wakefield acceleration. The weakly nonlinear dispe…
Synchrotron radiation from a curved plasma channel laser wakefield accelerator
J. P. Palastro, D. Kaganovich, B. Hafizi +5
A laser pulse guided in a curved plasma channel can excite wakefields that steer electrons along an arched trajectory. As the electrons are accelerated along the curved channel, th…
Reciprocity breaking during nonlinear propagation of adapted beams through random media
J. P. Palastro, J. Penano, W. Nelson +4
Adaptive optics (AO) systems rely on the principle of reciprocity, or symmetry with respect to the interchange of point sources and receivers. These systems use the light received…
Laser Accelerated Ions from a Shock Compressed Gas Foil
M. H. Helle, D. F. Gordon, D. Kaganovich +3
We present results of energetic laser-ion acceleration from a tailored, near solid density gas target. Colliding hydrodynamic shocks compress a pure hydrogen gas jet into a 70 μm t…
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…
