Abstract

We present a theory on harmonic generation by relativistic plasma resonance mechanism in an inhomogeneous laser plasma. We find a transverse component of the resonance–enhanced electric field and electron velocities near the plasma critical density and calculate the nonlinear current as the source of the harmonic generation in vacuum. We obtain the power-law spectra of the radiation field and discuss their characteristics depending on the laser-plasma parameters.
