Laser beat-wave accelerator for ultra-high energies
Parallel intense laser beams ..omega../sub 0/,k/sub 0/ and ..omega../sub 1/,k/sub 1/ shone on a plasma with frequency separation equal to the electron plasma frequency ..omega.. /SUB pe/ is capable of creating a coherent large longitudinal electric field E /SUB L/ = UPSILON1 /SUP 1/2/ mc ..omega.. /SUB pe/ /e of the order of 1-10GeV/cm for plasma density 10/sup 18 -20/cm/sup -3/ through the forward Raman scattering. A concept of applying this process to an ultra-high energy (100-1000 TeV range) accelerator is considered. Associated physics questions such as the laser beam propagation, self-trapping, filamentation, the longitudinal dephasing are discussed. As a method to overcome the longitudinal dephasing, the relativistic forward Brillouin scattering process is proposed, where the frequency separation of two lasers is now ..omega.. /SUB pi/ with ..omega.. /SUB pi/ being the ion plasma frequency.
