Mid- and Far-Infrared Supercontinuum Generation in Bulk Tellurium Spanning from 5.3 m to 32 m
Daniel Matteo, Sergei Tochitsky, Chan Joshi
Supercontinuum generation is performed in the bulk semiconductor tellurium (Te) with a high-power picosecond CO laser at peak intensities up to 20 GW/cm. The spectrum spans…
High average power ultrafast laser technologies for driving future advanced accelerators
Leily Kiani, Tong Zhou, Seung-Whan Bahk +34
Large scale laser facilities are needed to advance the energy frontier in high energy physics and accelerator physics. Laser plasma accelerators are core to advanced accelerator co…
Observation of breakdown wave mechanism in avalanche ionization produced atmospheric plasma generated by a picosecond CO laser
E. Welch, D. Matteo, S. Tochitsky +2
Understanding the formation and long-timescale evolution of atmospheric plasmas produced by ultrashort, long wavelength IR (LWIR) pulses is an important but partially understood pr…
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…
Laser-driven Collisionless Shock Acceleration of Ions from Near-critical plasmas
S. Tochitsky, A. Pak, F. Fiuza +5
This paper overviews experimental and numerical results on acceleration of narrow energy spread ion beams by an electrostatic collisionless shockwave driven by 1 um (Omega EP) and…
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…
Ion acceleration from laser-driven electrostatic shocks
F. Fiuza, A. Stockem, E. Boella +6
Multi-dimensional particle-in-cell simulations are used to study the generation of electrostatic shocks in plasma and the reflection of background ions to produce high-quality and…
Laser-driven shock acceleration of monoenergetic ion beams
F. Fiuza, A. Stockem, E. Boella +7
We show that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma…
