Variation of the EC and the DI counts with time. The ω–2ω CRTC fields are of intensity (a) 3.0 × 1014 W/cm2, (b) 6.0 × 1014 W/cm2, (c) 9.0 × 1014 W/cm2, and (d) 13.4 × 1014 W/cm2, respectively. The laser wavelength is 1575 nm and the two colors are of equal intensity. The x component of the electric field is marked by light gray lines.
