Control of odd and even harmonic generation by bichromatic elliptically polarized fields

Abstract Using the CO molecule as target, we investigate high-order harmonic generation by a bichromatic elliptically polarized laser field. This field consists of two components with commensurable frequencies and mutually orthogonal semi-major axes. Both odd even harmonics are emitted their ellipticity can be large depending on values laser-field parameters. It is often case that subsequent substantially different so that, in order to produce series similar ellipticity, it beneficial if emission or suppressed. In this paper explore how achieved using relative phase control For some these parameters possible comb ellipticity. These later employed for various applications example which an attosecond pulse train.
