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…
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…
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…
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…
A nonlinear plasma retroreflector for single pulse Compton backscattering
J. P. Palastro, D. Kaganovich, D. Gordon +4
Compton scattered x-rays can be generated using a configuration consisting of a single, ultra-intense laser pulse, and a shaped gas target. The gas target incorporates a hydrodynam…
