Orbital angular momentum enhanced laser absorption and neutron generation
Nicholas Peskosky, Nicholas Ernst, Miloš Burger +5
We experimentally demonstrate enhanced absorption of near relativistic optical vortex beams in plasmas to generate a record fast-neutron yield of …
High repetition rate (>= kHz) targets and optics from liquid microjets for the study and application of high intensity laser-plasma interactions
K. M. George, J. T. Morrison, S. Feister +11
High intensity laser-plasma interactions produce a wide array of energetic particles and beams with promising applications. Unfortunately, high repetition rate and high average pow…
Backward-propagating MeV electrons from W/cm laser interactions with water
John T. Morrison, Enam A. Chowdhury, Kyle D. Frische +6
We present an experimental study of the generation of MeV electrons opposite to the direction of laser propagation following the relativistic interaction at normal incidence…
Backward-Propagating MeV Electrons in Ultra-Intense Laser Interactions: Standing Wave Acceleration and Coupling to the Reflected Laser Pulse
Chris Orban, John T. Morrison, Enam D. Chowdhury +4
Laser-accelerated electron beams have been created at a kHz repetition rate from the {\it reflection} of intense ( W/cm), 40 fs laser pulses focused on a con…
High Repetition-Rate Wakefield Electron Source Generated by Few-millijoule, 30 femtosecond Laser Pulses on a Density Downramp
Z. -H. He, B. Hou, J. H. Easter +3
We report on an experimental demonstration of laser wakefield electron acceleration using a sub-TW power laser by tightly focusing 30-fs laser pulses with only 8 mJ pulse energy on…
Numerical Modeling of Radiation-Dominated and QED-Strong Regimes of Laser-Plasma Interaction
Igor V. Sokolov, Natalia M. Naumova, John A. Nees
Ultra-strong laser pulses can be so intense that an electron in the focused beam loses significant energy due to gamma-photon emission while its motion deviates via the radiation b…
