Currently, the Hamamatsu and Sandia Corporations use lithium niobate (LiNbO/sub 3/) in their crystal streak cameras. However, these systems have low resolution due to the low electrooptic coefficient of LiNbO/sub 3/, 30 x 10/sup -12/, which requires excessive voltage drives for the system. For a practical system, new tungsten bronze crystals such as barium niobate (Sr/sub 1-x/Ba/sub x/Nb/sub 2/O/sub 6/, or SBN:1-x (%) for short) must be used to achieve higher resolution and lower voltage drive requirements. Electrooptic coefficients of 400 x 10/sup -12/ m/V for SBN:60 and 1400 x 10/sup -12/ m/V for SBN:75 give improvements in resolution of 13 and 47, respectively. In this paper, we discuss the highlights of a light deflector developed at Lawrence Livermore National Laboratory (LLNL) for a streak camera that uses tungsten bronze crystals grown at Rockwell International Science Center. We address the design and fabrication of these crystals and include experimental results from our deflector experiment, the purpose of which is to determine the feasibility and expected performance of the crystal streak camera using tungsten bronze crystals. 9 refs., 4 figs., 3 tabs.
