Summary form only given. We analyze the generation of THz radiation when an intense, short laser pulse is mixed with its frequency-doubled counterpart in plasma1. The nonlinear coupling of the fundamental and the frequency-doubled laser pulses in plasma is shown to be characterized by a third order susceptibility which has a time dependence characteristic of the laser pulse durations. The THz generation...
Summary form only given. We evaluate the use of an intense ultra-short pulse laser and a high-power millimeter wave beam or fiber laser beam to create and maintain a remote flare within the atmosphere or on the surface of a dielectric. The remote flare generation concept involves propagating an intense ultra-short pulse laser to generate the initial breakdown, followed by a longer high-energy millimeter-wave...
Summary form only given. Laser driven accelerators such as the laser wakefield accelerator (LWFA) have tremendous advantages over conventional radio-frequency accelerators because of the ultra-high acceleration gradients (>100 GV/m) provided by the large amplitude relativistic plasma waves that are excited by the intense ultra-short laser pulse. These ultra-high gradients were demonstrated in the...
