Phys. Rev. Lett. 82, 4448–4451 (1999)Fast Compression of Laser Beams to Highly Overcritical PowersReceived 14 December 1998; published in the issue dated 31 May 1999 Laser beams can be strongly compressed in a plasma by stimulated Raman backscattering in a time short compared to the time scale for filamentation instabilities to develop. Such a compression should make feasible multi-MJ multi-exawatt-laser pulses technologically challenging by other means. The compression efficiency can reach nearly 100% at the Langmuir wave breaking limit. © 1999 The American Physical Society URL:
