Abstract

Abstract: We present a harmonic generation experiment using liquid H2O and D2O interrogated by a mid-infrared, 3.66 μm, laser at a maximum intensity of 8x1013 W/cm2. The unique aspects of the experiment include the long wavelength and short (9 cycle-110 fs) pulse duration of the laser as well as the near-resonant excitation of the H2O and D2O vibrational modes. We observe up to the 13th harmonic order in H2O and intensity scaling is consistent with a direct perturbative process up to the 9th harmonic order. Phase matching and resonant absorption are unable to account for the observed differences in harmonic yields between samples.

(a) Absorption profile of H2O (solid line-blue) and D2O (dash line-red). α is the linear absorption coefficient that obeys I = I0exp(-αz). (b) The MIR power spectrum. (c) Interferometric autocorrelation with a full width-at-half maximum (FWHM) of 110 fs.

The intensity of the harmonic yield is given by the peak of the harmonic field averaged to a single laser shot. The harmonic yields measured were the fifth (□-red), seventh (♦-green), ninth (○-blue) and eleventh (▼-orange).

Fig. 2
Fig. 2

(a) Heavy water (dash-red) and water (solid-blue) harmonic spectra at approximately 600 MW of MIR. The vertical bars along the wavelength axis are odd multiples of the fundamental field shown in Fig. 1 (b). (b) Efficiencies of water and heavy water considering collinear propagation with phase matching and resonant absorption. The vertical bars are the Imax/10 points within the thickness of the fluid. Shown on top is H2O (solid lines-blue) and bottom D2O (dashed lines-red). In both cases H5 is dark, H7 is medium, and H9 is light.
