The use of ultra-high intensity laser beams to achieve extreme material states in the laboratory has become almost routine with the development of the petawatt laser. Petawatt class lasers have been constructed for specific research activities, including particle acceleration, inertial confinement fusion and radiation therapy, and for secondary source generation (x-rays, electrons, protons, neutrons and ions). They are also now routinely coupled, and synchronized, to other large scale facilities including megajoule scale lasers, ion and electron accelerators, x-ray sources and z-pinches. The authors of this paper have tried to compile a comprehensive overview of the current status of petawatt class lasers worldwide. The definition of 'petawatt class' in this context is a laser that delivers >200 TW.

We show through experiments that a transition from laser wakefield acceleration (LWFA) regime to a plasma wakefield acceleration (PWFA) regime can drive electrons up to energies close to the GeV level. Initially, the acceleration mechanism is dominated by the bubble created by the laser in the nonlinear regime of LWFA, leading to an injection of a large number of electrons. After propagation beyond the depletion length, leading to a depletion of the laser pulse, whose transverse ponderomotive force is not able to sustain the bubble anymore, the high energy dense bunch of electrons propagating inside bubble will drive its own wakefield by a PWFA regime. This wakefield will be able to trap and accelerate a population of electrons up to the GeV level during this second stage. Three dimensional (3D) particle-in-cell (PIC) simulations support this analysis, and confirm the scenario.

“…As sketched in Figure 1, 60 TW near-infrared (800 nm) pulses from the Advanced Laser Light Source (ALLS) system 23 were propagated with a beam diameter of 8.5 cm to produce >900 filaments, starting after 2 m of propagation. They were overlapped at an angle of 4 with a 10 ns, 250 mJ frequency-quadrupled (266 nm) Nd:YAG laser, which was either focused (f ¼ 1.5 m) or collimated, resulting in a beam waist <0.1 cm and $1 cm diameter, respectively, in the interaction region.…”

Cooperative effect of ultraviolet and near-infrared beams in laser-induced condensation

We demonstrate the cooperative effect of near infrared (NIR) and ultraviolet (UV) beams on laser-induced condensation. Launching a UV laser after a NIR pulse yields up to a 5-fold increase in the production of nanoparticles (25-300 nm) as compared to a single NIR beam. This cooperative effect exceeds the sum of those from the individual beams and occurs for delays up to 1 ls. We attribute it to the UV photolysis of ozone created by the NIR pulses. The resulting OH radicals oxidize NO 2 and volatile organic compounds, producing condensable species. V C 2013 AIP Publishing LLC. [http://dx
