Abstract
Interferometric measurements of laser-produced channels in performed p lasmas show that in the presence of transverse plasma flow, the beam i s deflected when the transverse flow velocity is near the sound speed. For a line focus with peak intensity of 1.5 X 10(15) W/cm(2), a beam deflection of 10 degrees is observed, which agrees well with the resul ts of a three-dimensional hydrodynamics code.
