Abstract
Generation of circularly polarized high-order harmonics is studied with the targets of diatomic molecules subject to bichromatic counter-rotating circularly polarized laser fields. It is also found that with the driving field polarized perpendicular to the molecular axis, even-order harmonics polarized along the molecular axis can be generated by heteronuclear molecules, even if the permanent dipole moment of the molecules is very small.
