Phys. Rev. Lett. 105, 080402 (2010) [4 pages]Limitations on the Attainable Intensity of High Power LasersSee Also: Erratum Received 30 April 2010; published 18 August 2010 It is shown that even a single e-e+ pair created by a superstrong laser field in vacuum would cause development of an avalanchelike QED cascade which rapidly depletes the incoming laser pulse. This confirms Bohr’s old conjecture that the electric field of the critical QED strength ES=m2c3/eℏ could never be created. © 2010 The American Physical Society URL:
