Hot Electron and Pair Production from the Texas Petawatt Laser Irradiating Thick Gold Targets
Hot Electron Pair Production the Texas Petawatt Laser Thick Gold Targets Plasma Physics
2012/5/29
We present data from electron-positron pair production by an ultra-intense laser incident on solid Au targets with thickness between 1 and 4 mm. The experiment was performed at the Texas Petawatt Lase...

Abstract: Interaction of a frequency-chirped laser pulse with single protons and a hydrogen plasma cell is studied analytically and by means of particle-in-cell simulations, respectively. Feasibility ...
Single shot phase contrast imaging using laser-produced Betatron x-ray beams
Betatron x-ray beams
2011/9/5
Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, using the Betatron x-ray...
Comparison of hard x-ray production from various targets in air using a short pulse kHz laser with photon production from a high power multifilament laser beam from the same targets in air
multifilament short pulse kHz laser
2011/9/5
Over the last few years there has been much interest in the production of hard X-rays from various targets using a kHz short pulse laser at intensities above 1014Wcm-2 (A). Most of these studies have ...
Determination of Carrier-Envelope Phase of Relativistic Few-Cycle Laser Pulses by Thomson Backscattering Spectroscopy
Carrier-Envelope Phase ew-Cycle Laser Pulses Thomson Backscattering Spectroscopy
2011/9/2
A novel method is proposed to determine the carrier-envelope phase (CEP) of a relativistic few-cycle laser pulse via the central frequency of the isolated light generated from Thomson backscattering (...
High-quality proton bunch from laser interaction with a gas-filled cone target
proton bunch laser interaction gas-filled cone target
2011/9/2
Generation of high-energy proton bunch from interaction of an intense short circularly polarized(CP) laser pulse with a gas-filled cone target(GCT) is investigated using two-dimensional particle-in-ce...
