(a) Geometrical configuration with three incident beams that allows to flexibly control the phase-matching geometry; (b) Wave vector diagrams visualizing the phase mismatching/matching condition in three different cases. (b.1) and (b.3): phase-mismatched for all angles ; (b.2) phase-matched.

FIG. 2.

Wave-mixing setup to achieve phase matching for the third-order nonlinear process where . The incident angle is adjusted by a pair of mirrors ( and ) directing the beam at frequency .

FIG. 3.

Examples of phase matching curves for the intensity of the signal wave at a frequency as a function of the wavelength of one of the interacting beams. Left: three-beam configuration with and different values of between 4.5° and 6.1° (displayed as labels for the data sets). was kept fixed at 773 nm while was varied between 680 and 730 nm. Right: two-beam configuration with and . This time was kept fixed at 773 nm while was varied between 2350 and 2450 nm. Phase matching was obtained at to deliver a signal wave at .

FIG. 4.

Phase-matching data plotted as the angle vs the phase-matched wavelength corresponding to (solid rectangles) in the visible or (hollow rectangles) in the infrared for the two experimental configurations described in the text. The measurement errors are given by the actual size of the rectangles representing the data points. The solid and dashed curves are the result of a least-squares fit based on Eq. (2).

FIG. 5.

Refractive index dispersion obtained from the phase matching data using as a reference. The thickness of the curve and its darkness reflect the uncertainty in the refractive index dispersion caused by experimental errors in the determinations of the phase matching conditions.
