“…13 Less attention has been devoted to longitudinal shaping, although such shaping has been accomplished in both the optically driven and electrically driven configurations. [14][15][16][17] In this paper we consider primarily longitudinal shaping using a simple and inexpensive configuration, illustrated in Fig. 1.…”

Blast waves ignited in a supersonic flow are capable of producing density profiles useful for laser acceleration of electrons and ions. By using a ≈0.1 joule nanosecond laser as an igniter, and controlling the angle of incidence and timing of the ultra-intense femtosecond drive pulse, one can produce a variety of gas density profiles. A profile with an abrupt up-ramp followed by a gradual down-ramp leads experimentally to stable generation of 40 MeV electrons from a 10 TW drive pulse. A profile with a narrow high density region, and a steep density ramp on one side, is useful for magnetic vortex acceleration of ions. Simulations predict that such a profile can be generated from a laser ignited blast wave, and that 35 MeV protons are produced when a 100 TW pulse is focused into the shock front.

“…By scanning the interaction length with the same method, tomographic measurements were carried out to resolve the injection/acceleration process in laser wakefield accelerators and the amplification processes in plasma nonlinear optics (Pai et al 2006;Hsieh et al 2006;Chang et al 2007;Hsieh et al 2008). By adding a transverse heater pulse into the axicon-ignitor-heater scheme for producing a plasma waveguide, a variable three-dimensionally structured plasma waveguide was fabricated (Hung et al 2012). Applications of laser-fabricated plasma structures in plasma nonlinear optics, particle acceleration and ultra-intense mid-infrared pulse generation were also discussed (Pai et al 2010).…”

The presentations on laser plasma physics at the first AAPPS-DPP conference covered topics of inertial confined fusion physics and technologies, laboratory astrophysics and high-energy density physics, laser plasma-based particle acceleration (electrons and ions) and radiation, fundamental laser plasma physics, and related high-power laser system development. This report summarizes the major advances in these topics presented at the plenary and oral sessions.

“…In addition, the guiding effect of laser pulse in the plasma waveguide can be measured by the relay image system, setting the image plane at the exit of the plasma waveguide. The side scattering and the interferometry have been employed in previous experiments [33,[47][48][49]51] as powerful in situ diagnostics techniques for characterizing the density-modulated structure of fabricated plasma waveguides. Figure 9 illustrates the proof-of-principle results for measuring plasma columns that are created by passing 2.3 mJ, 40 fs linearly polarized laser pulses with 10 μm focal spot diameter through a nitrogen gas target.…”

Numerous applications in fundamental and applied research, security, and industry require robust, compact sources of x-rays, with a particular recent interest in monochromatic, spatially coherent, and ultrafast x-ray pulses in well-collimated beams. Such x-ray sources usually require production of high-quality electron beams from compact accelerators. Guiding a radially polarized laser pulse in a plasma waveguide has been proposed for realizing direct laser acceleration (DLA), where the electrons are accelerated by the axial electric field of a copropagating laser pulse (Serafim et al 2000 IEEE Trans. Plasma Sci. 28 1190). A moderate laser peak power is required for DLA when compared to laser wakefield acceleration, thus offering the prospect for high repetition rate operation. By using a density-modulated plasma waveguide for DLA, the acceleration distance can be extended with pulse guiding, while the densitymodulation with proper axial structure can realize the quasi-phase matching between the laser pulses and electrons for a net gain accumulation (
