“…Lasers are now routinely focused to an irradiance on target of I λ 2 = 10 21 W cm −2 µm 2 (Perry et al 1999;Danson et al 2004) (where I is the intensity and λ is the wavelength of the laser radiation). A number of new lasers promise many more order of magnitude increases in intensity in the near (Hooker et al 2006;Yanovsky et al 2008) and medium-term future (Gerstner 2007). This field has engendered a lot of interest and attention owing to the fact that it that has allowed the investigation of many novel relativistic plasma physics issues, ranging from compact particle accelerators (Tajima and Dawson 1979;Pukhov and Meyer-ter Vehn 2002;Mangles et al 2004;Geddes et al 2004;Faure et al 2004) to high energy density laboratory astrophysics (Ryutov et al 1999(Ryutov et al , 2001Ryutov and Remington 2003) and fast ignition inertial fusion.…”

In this paper, we have investigated the nonlinear propagating coupled Kinetic Alfven-acoustic waves in a low beta degenerate quantum plasma in the presence of trapped Fermi electrons using the quantum hydrodynamic (QHD) model. By using the two potential theory and the Sagdeev potential approach, we have investigated the formation of solitary structures for coupled kinetic Alfven-acoustic waves in the presence of quantum mechanically trapped electrons. We have shown that there are regions of propagation and non-propagation for such solitary structures. We have also highlighted the differences between the classical and quantum mechanically trapped electrons. Interestingly, it has been found that the nature of the nonlinearity for the quantum mechanically trapped electrons is different from its classical counterpart. The results presented here may have applications in white dwarf asteroseismology as well as next generation laserplasma experiments where low beta plasma condition is met.

“…Another amplification technique called Optical Parametric Chirped Pulse Amplification (OPCPA), based on the nonlinear interaction among laser beams in crystals, was suggested almost at the same time as the CPA and proved to be promising as well (Piskarskas et al, 1986). As a result of the increase in available laser intensities, exciting perspectives have been envisaged in different fields spanning from atomic to plasma and even nuclear and high-energy physics (Feder, 2010;Gerstner, 2007;Tajima et al, 2010).…”

The field of laser-matter interaction traditionally deals with the response of atoms, molecules and plasmas to an external light wave. However, the recent sustained technological progress is opening up the possibility of employing intense laser radiation to trigger or substantially influence physical processes beyond atomic-physics energy scales. Available optical laser intensities exceeding 10 22 W/cm 2 can push the fundamental lightelectron interaction to the extreme limit where radiation-reaction effects dominate the electron dynamics, can shed light on the structure of the quantum vacuum, and can trigger the creation of particles like electrons, muons and pions and their corresponding antiparticles. Also, novel sources of intense coherent high-energy photons and laserbased particle colliders can pave the way to nuclear quantum optics and may even allow for potential discovery of new particles beyond the Standard Model. These are the main topics of the present article, which is devoted to a review of recent investigations on high-energy processes within the realm of relativistic quantum dynamics, quantum electrodynamics, nuclear and particle physics, occurring in extremely intense laser fields.

“…1). Indeed laser systems capable of generating Exawatt (10 18 Watt) peak power levels are in the planning stages for potential construction sometime over the next decade [3,4]. However even the smaller scale Terawatt-level lasers which are now commonplace can be focused to high intensities such that the laser electric field immediately rips off electrons from the atoms it encounters -immediately forming a plasma.…”

International audienceOver the past several years there have been significant advances in research towards generating compact relativistic electron beams using high power short pulse laser produced plasmas (i.e., laser wakefield accelerators). In particular, an explosion of interest was generated in this field following the discovery in 2004 of a method to create such beams with low energy spread using a plasma bubble shaped wake. Recent work has increased the energy of these beams to the GeV range by extending the acceleration distance from a few millimetres to several centimeters. From both experimental and theoretical work, a more complete understanding of this plasma bubble regime for electron acceleration has also been obtained, enabling a significant improvement in the output electron beam quality and stability. There is ongoing work to further improve the parameters and stability of these beams with the goal of constructing table-top 4th generation sources of coherent x-ray radiation
