Large-amplitude plasma wave generation with a high-intensity short-pulse beat wave

Abstract : A short-pulse laser beat wave scheme for advanced particle accelerator applications is examined. A short, intense (3-ps, >10^18-W cm^-2) two-frequency laser pulse is produced by use of a modified chirped-pulse amplification scheme and is shown to produce relativistic plasma waves during interactions with low-density plasmas. The generation of plasma waves was observed by measurement of forward Raman scattering. Resonance was found to occur at an electron density many times that expected, owing to ponderomotive displacement of plasma within the focal region.
