Figure 2.2 Calculated data of the harmonic spectra from fullerene plasma
in the case of (a,b) 780 nm and (c) 1300 nm probe radiation. The pulse
durations are (a) 2 optical cycles (5.2 fs), (b) 12 optical cycles (31 fs), and
(c) 8 optical cycles (34 fs). Reproduced from Ref. 24 with permission from

it has been argued that they add destructively in the forward
direction or that they show a transient nature and are thus
overwhelmed by the presented odd harmonics [34, 35].
The calculations showed ...
