    Summary Report Of Working Group 8: Laser Technology For Laser-Plasma Accelerators
    (2012-06) Gaul, E.; Toth, C.; Gaul, Erhard; Tóth, Csaba
    Laser Technology has long been the limiting and the enabling step for laser plasma accelerators. The work presented here addressed the current and near future laser technology relevant to particle acceleration as well as laser technology challenges for future accelerator facilities. Many laser facilities are operating or will be operating shortly at high intensity, high peak power, and with good beam parameters.

    Towards Single-Shot Characterization Of Near-Resonant Lwfa In A Differentially-Pumped Gas Cell
    (2004-06) Matlis, N.; Downer, M.; Matlis, Nicholas; Downer, Michael
    We report on progress in the development of a single-shot diagnostic for measuring near-resonant laser-driven wakefields. The development entails the following critical steps: 1. Increase in laser pulse energy 2. development and characterization of a differentially pumped gas cell 3. development of a single-shot diagnostic with low phase noise 4. analysis of laser/plasma parameter space for maximizing the measured phase shift. As a result of this development we expect to be have detection sensitivity of 50 - 100 mrad and we expect to be able produce and measure wakefields with dne/nesimilar to1 and phase shifts of several hundred mrad.
