FIG. 1.

Time-of-flight spectrum of SF irradiated by 5 fs pulses of peak intensity 3.5 × 1015 W cm−2. Fifty thousand laser shots were used. For clarity, the full mass range up to 150 amu is shown in two separate panels. The same spectral features were obtained when 11 fs and 22 fs pulses of the same peak intensity were used.

FIG. 2.

Distribution of kinetic energies (in the center-of-mass frame) of F+ fragment ions from SF irradiated by 5 fs pulses of peak intensity 3.5 × 1015 W cm−2. The inset shows ion-pair spectra where τ denote times of flight. The higher density of dots indicates formation of SF + and F+ ion pairs, with the separation between the regions of high density dots being a measure of the kinetic energy release accompanying formation of this ion pair.

FIG. 3.

Distribution of kinetic energies (in the center-of-mass frame) of F2+ fragment ions from SF irradiated by 5 fs pulses of peak intensity 3.5 × 1015 W cm−2.

Image of FIG. 4.
FIG. 4.

Field-free potential energy curve of SF and a field-dressed potential energy curve of the ground electronic state of SF +. The static optical field corresponded to a peak laser intensity of 1 × 1015 W cm−2.
