Resonant noninear refraction of 4-5 m light in CO and CO gas
Jeremy Pigeon, Dana Tovey, Sergei Tochitsky +7
The resonant nonlinear refraction of 4-5 m light in CO and CO gas at a peak intensity of 15 MW/cm was demonstrated using time- and frequency-resolved measurements of sel…
Lasing in 15 atm CO2 cell optically pumped by a Fe:ZnSe laser
Dana Tovey, Jeremy Pigeon, Sergei Tochitsky +7
10 μm lasing is studied in a compact CO2-He cell pressurized up to 15 atm when optically pumped by a ~50 mJ Fe:ZnSe laser tunable around 4.3 μm. The optimal pump wavelength and par…
Predominant Contribution of Direct Laser Acceleration to High-Energy Electron Spectra in a Low-Density Self-Modulated Laser Wakefield Accelerator
P. M. King, K. Miller, N. Lemos +12
The two-temperature relativistic electron spectrum from a low-density (~cm) self-modulated laser wakefield accelerator (SM-LWFA) is observed to transition be…
Collisionless shock acceleration of narrow energy spread ion beams from mixed species plasmas using 1 m lasers
A. Pak, S. Kerr, N. Lemos +15
Collisionless shock acceleration of protons and C ions has been achieved by the interaction of a 10 W/cm, 1 m laser with a near-critical density plasma. Ablati…
High-power, mid-infrared, picosecond pulses generated by compression of a CO2 laser beat-wave in GaAs
J. J. Pigeon, S. Ya. Tochitsky, C. Joshi
We report on the generation of a train of ~ 2 ps, 10 um laser pulses via multiple four-wave mixing and compression of an infrared laser beat-wave propagating in the negative group…
Sub-femtosecond electron bunches created by direct laser acceleration in a laser wakefield accelerator with ionization injection
N. Lemos, J. L. Shaw, K. A. Marsh +1
In this work, we will show through three-dimensional particle-in-cell simulations that direct laser acceleration in laser a wakefield accelerator can generate sub-femtosecond elect…
