Phys. Rev. E 75, 026404 (2007) [5 pages]Compression of powerful x-ray pulses to attosecond durations by stimulated Raman backscattering in plasmasReceived 9 May 2006; published 20 February 2007 Backward Raman amplification (BRA) in plasmas holds the potential for longitudinal compression and focusing of powerful x-ray pulses. In principle, this method is capable of producing pulse intensities close to the vacuum breakdown threshold by manipulating the output of planned x-ray sources. The minimum wavelength limit of BRA applicability to compression of laser pulses in plasmas is found. © 2007 The American Physical Society URL:
