    Sandia National Laboratories researchers use wavefront imaging taken at 35,000 frames per second to analyze blast-wave dynamics invisible to the eye and determine how well nuclear weapons could survive a shock wave.
    The tests demonstrate how well nuclear weapons could survive the shock wave of a blast from an enemy weapon.

    FIGURE 1. Huge electrical currents generate arcs and sparks on the Z machine at Sandia National Labs. The bright objects in the foreground are the laser triggered gas switches.
    Computer-controlled motorized mirror mounts enable rapid realignment of beam-steering optics between discharges at Sandia National Labs' Z machine.
    FIGURE 1. A basic field-effect transistor consists of a source and drain of charge carriers that connect to a channel controlled by a gate (top). A fundamental standing-charge-density oscillation, known as a plasmon, sloshes between two boundaries (bottom left). Increased current causes a higher harmonic of the fundamental plasmon, splitting the group in two (bottom right). Like a spring constant, increasing the carrier density in the channel increases the resonant frequency.
    Plasmon-based grating-gate detectors based on hot-electron bolometer mixers are being explored as tunable detectors of terahertz radiation—the next big thing in security applications...

    Driven by an actuator (top, gray), two pusher rings (gold and violet) deform a flat mirror into a paraboloid, compensating for thermal-lens effects occurring in a high-energy-laser rod amplifier. The focal length of the mirror can be varied from infinity down to 5 m (bottom). The interferometrically measured wavefront profile has the desired paraboloidal shape (bottom, 3-D color plot).
    To counter thermal lensing in high-energy-laser rod amplifiers, researchers at Sandia National Laboratories (Albuquerque, NM) have developed a deformable mirror that does one ...
