Abstract
By use of a hydrocode it is shown that the interaction of high intensity light with an expanding plasma surface produces a positive plasma cloud followed by a negative plasma cloud. This result, which is opposite to that without the laser light, is the result of the nonlinear ponderomotive force. This theory explains the experimental observations made at Soreq. These double layers were measured with the help of a new electro-optical technique (developed at Soreq) in which a streak camera is coupled to a Pockels cell with a fast risetime. This technique can improve the time resolution of the high voltages observed in laser-produced plasmas by two orders of magnitude in comparision to the best oscilloacope measurements.
