We use a 5-level system to investigate the HHG spectrum emitted by an atom driven by a linearly or elliptically polarized laser field.For this model the Schrodinger equation is numerically solved and we study the dipendence of the spectra, harmonic intensity andpolarization of emitted radiation on the laser field ellipticity. Studying the intensity of the emitted radiation we find that un alsoderhigh laser ellipticity the harmonic emission is greatly reduced; the analysis of results shows that the harmonic intensity and theemitted radiation depend on the laser ellipticity.
