Single-Pulse Driven, Large-Aperture, 2x1 Array Plasma-Electrodes Optical Switch For Sg-Ii Upgrading Facility

We demonstrate the design and performance of an optical switch that has been constructed for the SG-II upgrading facility. The device is a longitudinal, potassium di-hydrogen phosphate (KDP), 360 mmx360 mm aperture, and 2x1 array electro-optical switch driven by a 20 kV output switching-voltage pulse generator through two plasma electrodes produced at the rise edge of the switching-voltage pulse. The results show that the temporal responses and the spatial performance of the optical switch fulfill the operation requirements of the SG-II upgrading facility.
