“…[1][2][3][4] In LWFA, the affected plasma electrons can be almost completely expelled by the laser pulse, leaving behind the laser pulse a cavity or "bubble" containing only ions. The resulting space-charge field in the back of the bubble can trap and accelerate the electrons trapped there to high speed and form a high-energy electron bunch, [5][6][7] with the narrow energy spread and small spatial divergence.…”

The interaction of two energetic electron bunches generated in the wakefields of two intense intersecting laser pulses in rarefied plasmas is investigated using particle-in-cell simulations. It is found that, with suitable intersection angle between the two laser pulses, the initially independent wakefield accelerated electron bunches can merged into a single one with high charge, energy, and narrow energy spread. The dynamics of the laser-pulse intersection and wake-bubble merging process is also investigated, and the crucial roles of the intersection angle are pointed out and analyzed.

“…3 Therefore, we begin with a one-dimensional analysis of the bubble field. Considering a circularly polarized, plane-wave laser pulse of amplitude a = eA / mc 2 propagating in the x direction, leaving a bubble behind it with a wake field of scalar potential ͑͒ = ͑͒ / mc 2 , the phase velocity ␤ ph = v ph / c of the wake equals the group velocity of the laser pulse.…”

“…[1][2][3] The recent development of the "bubble" regime 4-10 has demonstrated the capability of generating high-quality electron beams with beam energy up to 1 GeV, 10 and relatively small energy spread and emittance approaching that from a conventional accelerator. Driven by an intense electron beam, an energy gain of 2 GeV is obtained over a distance of 10 cm.…”

The triggering of wave-breaking in a three-dimensional laser plasma wake (bubble) is investigated. The Coulomb potential from a nanowire is used to disturb the wake field to initialize the wave-breaking. The electron acceleration becomes more stable and the laser power needed for self-trapping is lowered. Three-dimensional particle-in-cell simulations were performed. Electrons with a charge of about 100pC can be accelerated stably to energy about 170MeV with a laser energy of 460mJ. The first step towards tailoring the electron beam properties such as the energy, energy spread, and charge is discussed.

“…Recently, laser-plasma accelerators as an alternative to the conventional particle accelerators, have attracted more attention due to the huge acceleration rate, and thus they are potential for making compact accelerators. [1][2][3] In the last decade, different mechanisms have been proposed to accelerate the charged particles via laser-plasma interactions. [4][5][6][7][8][9][10] Depending on the species of particles (electrons or ions), a static electric field (ion acceleration) or a running electric wave (electron acceleration) is used to accelerate the particles.…”
