Relativistic laser–plasma interactions
By focusing petawatt peak power laser light to intensities up to 1021 W cm−2, highly relativistic plasmas can now be studied. The force exerted by light pulses with this extreme intensity has been used to accelerate beams of electrons and protons to energies of a million volts in distances of only microns. This acceleration gradient is a thousand times greater than in radio-frequency-based acce...
متن کاملMicroengineering Laser Plasma Interactions at Relativistic Intensities.
We report on the first successful proof-of-principle experiment to manipulate laser-matter interactions on microscales using highly ordered Si microwire arrays. The interaction of a high-contrast short-pulse laser with a flat target via periodic Si microwires yields a substantial enhancement in both the total and cutoff energies of the produced electron beam. The self-generated electric and mag...
متن کاملRelativistic soliton formation in laser magnetized plasma interactions
The laser plasma interactions in the presence of strong magnetic field are studied by employing particle-in-cell simulations. Simulations show that the energy absorption of strong laser pulse is mainly characterized by the electron cyclotron resonance heating (ECRH) when the magnetic field is large enough. However, it is found that for a weaker magnetic field, a standing or moving soliton can b...
متن کاملElectron and Photon Production From Relativistic Laser-Plasma Interactions
The interaction of short and intense laser pulses with plasmas is a very efficient source of relativistic electrons with tunable properties. In low density plasmas, we observed bunches of electrons up to 200 MeV, accelerated in the wake field of the laser pulse. Less energetic electrons (tens of MeV) have been obtained, albeit with a higher efficiency, during the interaction with a solid target...
متن کاملHosing instability in the blow-out regime for plasma-wakefield acceleration.
The electron hosing instability in the blow-out regime of plasma-wakefield acceleration is investigated using a linear perturbation theory about the electron blow-out trajectory in Lu et al. [in Phys. Rev. Lett. 96, 165002 (2006)10.1103/PhysRevLett.96.165002]. The growth of the instability is found to be affected by the beam parameters unlike in the standard theory Whittum et al. [Phys. Rev. Le...
