Even order harmonics generation of the laser radiation due to electron-ion collisions in a plasma embedded in a constant electric field is investigated theoretically. Even harmonics are generated because the presence of a static electric field removes the invariance of the electron distribution func

โฆ Synopsis
Half integer (3/20,, 1/20,) harmonics generation under oblique incidence of thepump-waveon the spcrtinlly inhomogeneous plasma is theoretically investigated. Harmonica generation is ronnected with the two-plasmon convective instability excitation near the quarter-critical density. Harmonics spectra and intensities depend eseentially on the pump wave polarization. Inpnrticular, significant hnrmonics spectra broadening arises under the p-polarized pump wave.
