Frolov, M. V.; Manakov, N. L.; Minina, A. A.; Vvedenskii, N. V.; Silaev, A. A.; Ivanov, M. Yu.; and Starace, Anthony F., We study control of high-order harmonic generation (HHG) driven by time-delayed, few-cycle ω and 2ω counterrotating mid-IR pulses. Our numerical and analytical study shows that the time delay between the two-color pulses allows control of the harmonic positions, both those allowed by angular momentum conservation and those seemingly forbidden by it. Moreover, the helicity of
