英文摘要 | The polarization of high-order harmonic generation in H-2(+) driven by a counterrotating bichromatic omega/3 omega circularly polarized laser field is investigated theoretically. The elliptically polarized harmonics are characterized by ellipticity and rotation angle, where the latter is expanded to [-pi/2, pi/2] by an optimized definition. We find a critical alignment angle where the ellipticity of high-energy harmonics is almost the same, so an attosecond pulse train with a high degree of polarization can be synthesized. In addition, we find that the rotation angle is always different from the alignment angle by 90 degrees with a small deflection. Thus, we propose a scheme to control the harmonic polarization state by the molecular alignment angle. |
