Abstract
The concept of a longitudinal electrooptical switch utilizing plasma electrodes was recently scaled-up to the 26- × 26-cm aperture using a 1cm thick KDP crystal.1 This device has an order of magnitude larger open area and a factor of ~30 higher crystal aspect ratio than Poekels cells of the conventional ring-electrode design. Optical switching speeds of better than 30 nsec over the entire aperture have been achieved. The plasma electrode design is scalable to larger apertures (≥ 1 m) and is potentially of great importance for future development of high-energy laser drivers for inertial confinement fusion.
