Towards Intelligent Control of MeV Electrons and Protons from kHz Repetition Rate Ultra-Intense Laser Interactions
Nathaniel Tamminga, Scott Feister, Kyle D. Frische +8
Ultra-intense laser-matter interactions are often difficult to predict from first principles because of the complexity of plasma processes and the many degrees of freedom relating…
Experimental observation and computational modeling of radial Weibel instability in high intensity laser-plasma interactions
Gregory K. Ngirmang, John T. Morrison, Kevin M. George +5
When a relativistic intensity laser interacts with the surface of a solid density target, suprathermal electron currents are subject to Weibel instability filamentation when propag…
3D PIC simulations of electron beams created via reflection of intense laser light from a water target
Gregory K. Ngirmang, Chris Orban, Scott Feister +4
We present 3D Particle-in-Cell (PIC) modeling of an ultra-intense laser experiment by the Extreme Light group at the Air Force Research Laboratory (AFRL) using the PIC code LSP. Th…
Relativistic electron acceleration by mJ-class kHz lasers normally incident on liquid targets
Scott Feister, Drake R. Austin, John T. Morrison +10
We report observation of kHz-pulsed-laser-accelerated electron energies up to 3 MeV in the - (backward) direction from a 3 mJ laser interacting at normal incidence…
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…
A Novel Femtosecond-Gated, High-Resolution, Frequency-Shifted Shearing Interferometry Technique for Probing Pre-Plasma Expansion in Ultra-Intense Laser Experiments
S. Feister, J. A. Nees, J. T. Morrison +4
Ultra-intense laser-matter interaction experiments (>10 W/cm) with dense targets are highly sensitive to the effect of laser "noise" (in the form of pre-pulses) preced…
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…
