Electron penetration heating in turbulent magnetic loops driven by nonrelativistic laser-plasma interaction
Zheng Gong, Sida Cao, Caleb Redshaw +1
Using particle-in-cell simulations to study nonrelativistic laser pulse propagation in a under-critical plasma, we identify a novel mechanism that occurs during the growth of turbu…
Dispersive Properties of Plasma Diffraction Gratings: Towards Plasma-Based Laser Pulse Compression
Victor M. Perez-Ramirez, Michelle M. Wang, Ke Ou +10
The standard architecture for a high-peak-power femtosecond laser is chirped pulse amplification using diffraction gratings for compression; the damage threshold of the compression…
Intense tunable terahertz radiation from phase-matched difference frequency generation in strongly magnetized plasmas
Sida Cao, Matthew R. Edwards
High-energy terahertz pulses are challenging to produce due to the low conversion efficiency and limited optical damage threshold of nonlinear crystals. Here, we describe the high-…
Phase-Matched Harmonic Generation in Strongly Magnetized Plasma
S. Cao, M. R. Edwards
Harmonic generation in underdense spatially homogeneous plasma is generally expected to be inefficient: in an unmagnetized uniform plasma the fundamental and its harmonics cannot b…
Laser wakefield acceleration of ions with a transverse flying focus
Zheng Gong, Sida Cao, John P. Palastro +1
The extreme electric fields created in high-intensity laser-plasma interactions could generate energetic ions far more compactly than traditional accelerators. Despite this promise…
