Measured circular harmonics from elliptical driver pulses in Si. a Polarizer scan of HH9 (ε = 0.5, θ = ΓX + 30°) and HH7 (ε = 0.3, θ = ΓX + 5°). The solid lines are sin-square fits. b Harmonic ellipticities |εHH| versus driving intensity for ε = 0.4 and θ = ΓX + 10°. c Yields of HH5–HH9 for exemplary cases of circular harmonic polarization. The harmonic yields are normalized to the maximum harmonic yield for ε = 0 (indicated by the light color bars)
