We propose a strategy to orient linear molecules with combined linearly and elliptically polarized two-color laser fields. The elliptically polarized field is used to suppress the symmetric alignment potential when increasing the asymmetric orientation potential. The strategy is useful for general molecules with smaller hyperpolarizability anisotropy and larger polarizability anisotropy.
