FIG. 1.

Typical result for the time evolution of the electric field. The laser frequency is 0.057 a.u. (3.1 eV) and the peak laser intensity is 8.3 × 1012 W/cm2. (a)The blue dashed line represents the applied electric field and the red solid line represents the electric field in bulk diamond. (b) The energy transfer to electrons. (c) The HHG spectrum calculated by the Fourier transformation of the electronic current.

FIG. 2.

The time evolution of the electronic current generating the (a) 1st, (b) 3rd, (c) 5th, (d) 7th, (e) 9th, and (f) 11th harmonics. Each current is calculated by the inverse Fourier transformation of the current.

FIG. 3.

Laser intensity dependence of HHG spectrum with frequencies of (a) 0.057 a.u. (1.55 eV) and (b) 0.114 a.u. (3.1 eV). The intensity of the HHG spectrum is normalized by the fundamental intensity.
