Normalized harmonic intensity as a function of ellipticity of H21 (black squares), H27 (red circles), H31 (blue triangles), H37 (pink inverted triangles), and H39 (green diamonds) from N₂ molecules aligned (a) parallel and (b) perpendicular to the major axis of the elliptical polarization plane. Peak intensity of the 800 nm driving laser is 2.3 × 10 14 W / cm 2 .
