Twodimensional beat wave acceleration simulation
Abstract
Finite laser beam particle simulations of beat wave acceleration show that a coherent plasma wave excited by two colinear laser beams at a difference frequency equal to the plasma frequency can produce maximum electron energies as predicted by simple one dimensional theory. The time to saturation amplitude of the plasma wave electric field agrees with the RosenbluthLiu theory. Stimulated Raman scattering does not appear to degrade the electron acceleration process. Eventually selffocussing and filamentation limit the lifetime of the coherent plasma wave to tens of picoseconds for an intense CO2 laser beam.
