ABSTRACT
A large-amplitude surface plasma wave (SPW) over a metal-vacuum interface Ohmically heats the electrons and undergoes nonlinear absorption. The attenuation rate increases with the local SPW amplitude. The enhanced electron temperature leads to stronger thermionic emission of electrons. At typical Nd:glass laser intensity IL=7 GW/cm2, if one takes the amplitude of the SPW to be ≈6 times the amplitude of the laser, one obtains the thermionic electron emission current density J=200 A/cm2. However, the emission current density decreases with propagation distance at a much faster rate than the SPW amplitude and electron temperature.
