MP3 White Paper 2021 -- Research Opportunities Enabled by Co-locating Multi-Petawatt Lasers with Dense Ultra-Relativistic Electron Beams
Sebastian Meuren, David A. Reis, Roger Blandford +11
Novel emergent phenomena are expected to occur under conditions exceeding the QED critical electric field, where the vacuum becomes unstable to electron-positron pair production. T…
Generating optical supercontinuum and frequency comb in tenuous plasmas
Kenan Qu, Nathaniel J. Fisch
There are several mechanisms by which the frequency spectrum of a laser broadens when it propagates at near-relativistic-intensity in tenuous plasma. Focusing on one dimensional ef…
Modulation-Slippage Tradeoff in Resonant Four-Wave Upconversion
Alec Griffith, Kenan Qu, Nathaniel J. Fisch
Following up on a proposal to use four-wave mixing in an underdense plasma at mildly relativistic laser intensities to produce vastly more energetic x-ray pulses [V. M. Malkin and…
Optical phase conjugation in backward Raman amplification
Qing Jia, Kenan Qu, Nathaniel J. Fisch
Compression of an intense laser pulse using backward Raman amplification (BRA) in plasma, followed by vacuum focusing to a small spot size, can produce unprecedented ultrarelativis…
On Seminal HEDP Research Opportunities Enabled by Colocating Multi-Petawatt Laser with High-Density Electron Beams
Sebastian Meuren, Phil H. Bucksbaum, Nathaniel J. Fisch +7
The scientific community is currently witnessing an expensive and worldwide race to achieve the highest possible light intensity. Within the next decade this effort is expected to…
Laser frequency upconversion in plasmas with finite ionization rates
Kenan Qu, Nathaniel J. Fisch
Laser frequency can be upconverted in a plasma undergoing ionization. For finite ionization rates, the laser pulse energy is partitioned into a pair of counter-propagating waves an…
