Petawatt Laser Achieves Record Power

Facebook X LinkedIn Email
BERKELEY, Calif., Aug. 1, 2012 — The Berkeley Lab Laser Accelerator (BELLA) laser system has generated a record petawatt of power in a pulse just 40 fs long at a pulse rate of 1 Hz — one pulse every second. The BELLA design is based on years of laser plasma accelerator research performed by the US Department of Energy’s Lawrence Berkeley National Laboratory’s Accelerator and Fusion Research Div.’s (AFRD) Lasers and Optical Accelerator Systems Integrated Studies (LOASIS) program. In contrast to conventional accelerators, laser plasma accelerators produce electron density waves that move through a...Read full article

    laser plasma
    A plasma produced by the interaction of an intense laser pulse with a material surface. Production of ionized particle with high intensity radiation. The narrow path of the intense field produces a plasma channel. The LIPC (laser-induced plasma channel) laser has been adapted towards electroshock weapons as well as induced lightning.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
