Abstract

In this paper, a nanosecond speed KTN beam deflector is presented. The beam deflector is based on the combination of pre-injected space charge field and high speed (nanosecond) switching field. A beam deflection speed on the order of nanosecond was demonstrated, which was fastest beam deflection speed reported so far. The experimentally results confirmed that the speed limitation of KTN beam deflector was not limited by the electro-optic (EO) effect itself but the driving electric source and circuit. With a faster speed driving source and circuit, it is possible to develop GHz frequency beam deflector.
