Abstract
An intense short laser pulse incident on a metallic
target produces an overdense
plasma and excites a plasma surface wave via stimulated Compton scattering.
The pump and the surface wave exert a beat-frequency ponderomotive force on
the electrons in the skin layer, driving a heavily damped quasimode. The
density perturbations due to the quasimode couple with the
oscillatory velocity
due to the pump to drive the surface wave. The growth period
for the process
turns out to be about 0.5 ps at a Nd[ratio ]glass laser intensity of
1016W cm−2 and a
plasma density of 1.5 times the critical value.
