Abstract
A high power laser of frequency ω incident on a rippled metal surface gives rise to oscillatory electron velocity v2ω at the second harmonic in the skin layer. Its coupling with the surface ripple (modeled as a density ripple) of suitable wave number produces a nonlinear current, driving a surface plasma wave at frequency 2ω.
