Unruh Radiation with Ultra - Intense Lasers ?
ABSTRACT We point out that using the state-of-the-art (or soon-to-be) intense ultrafast laser technology, violent acceleration that may be suitable for testing general relativistic e ects can be realized through the interaction of a high intensity laser with a plasma. In particular, we demonstrate that the Unruh radiation is detectable, in principle, beyond the conventional radiation (most nota...
متن کاملRelativistic positron production with ultra-intense short-pulse lasers
Ultra-intense laser interactions with solid foils are studied as a means to produce relativistic positron plasmas, which has been proposed as a potential laboratory for understanding positron-electron plasma aspects of gamma-ray bursts [1]. Initial experiments with high energy Nd:glass lasers have revealed a strong dependence of the positron yield, and energy distribution, on the thin-foil targ...
متن کاملKinetic Modeling of Ultra-Intense X-Ray Laser-Matter Interactions
Although hard-x-ray free-electron lasers (XFELs) have only existed since 2009 when the Linac Coherent Light Source (LCLS) at Stanford created its first laser pulse, their capabilities have already had a profound impact on the physical, chemical, and biological sciences. The LCLS can produce extremely short (< 100 fs) millijoule x-ray laser pulses with more than 1012 photons each [1], making it ...
متن کاملRadiative reaction in ultra-intense laser–atom interaction
The influence of the radiation of an initially bound electron in an ultra-intense laser field on its dynamics and the consequent corrections to its spectral response are investigated within the relativistic classical Lorentz–Dirac approach. We find appreciable damping of the electron motion in the direction of polarization of the laser field, and a consequent reduction of the electron oscillati...
متن کاملEnergetic Proton Generation in Ultra-Intense Laser-solid Interactions
An explanation for the energetic ions observed in the PetaWatt experiments is presented. In solid target experiments with focused intensities exceeding 10 W/cm, high-energy electron generation, hard bremsstrahlung, and energetic protons have been observed on the backside of the target. In this report, we attempt to explain the physical process present that will explain the presence of these ene...
