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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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 ...
