FIG. 2.

An example of the PE signals detected in two phase-matched directions at . The PEPS value is measured to be 18 fs. The maximum of signal is about 15% higher than the signal value at .

FIG. 3.

Absorption spectrum of DPA (see scheme of the molecular structure) in ethanol (solid black line) and the excitation pulse spectrum (dashed red line). Inset: spectral amplitude and phase of the UV pulses at the sample position.

FIG. 4.

PE signals for DPA in ethanol (solid black line), DPA in cyclohexane (dashed blue line), pTP in ethanol (dotted red line) and pure ethanol (dashed-dotted green line), detected in the phase-matching direction at (a) and (b) . Signals are shifted to overlap their maxima at .

FIG. 5.

PEPS trace of DPA in ethanol, fitted by a monoexponential decay plus an offset.

Image of FIG. 6.
FIG. 6.

An example of dependence of the PEPS offset on the chirp, obtained by increasing the length of glass in the compression stage prism through which the beam passes. The measurements were done on DPA in ethanol. .

FIG. 7.

Nonresonant signal from pure ethanol in two phase-matched directions .

FIG. 8.

Interaction of chirped pulses in the PE setup. In this scheme, pulses are positively chirped. ”r” refers red chirp and ”b” refers to blue chirp of the pulses. is the average detuning of the interacting components of the first and second pulses from defined by Eq. (2).

FIG. 10.

Normalized intensity of nonlinear signal as a function given by Eq. (5). Inset: the range of possible values of given by our experimental conditions is marked by a small red square.

Image of FIG. 11.
FIG. 11.

Normalized intensity of nonlinear signal as a function for the case of 0.3 OD (real condition, dashed red line), 0 OD (nondepleted pump, solid black line), and 1 OD (dotted blue line).
