Abstract

High-harmonic generation (HHG) of femtosecond lasers produces unique short-wavelength light pulses with femtosecond to attosecond duration. However, free electrons in the partially ionized gas medium are known to prevent phase matching and limit upconversion to low-energy harmonics only. We have demonstrated experimentally and theoretically an unconventional phase-matching scheme: extending the HHG phase matching cutoff by controlling the rapid self-defocusing effect of the driving laser. This method takes advantage of the additional intrinsic atomic dipole phase mismatch introduced by the rapid laser defocusing. This phase can be precisely controlled by adjusting the aperture of a simple iris, which truncates the input beam, to correctly compensate free-electron dispersion, resulting in tunable harmonic energy and phase matching cutoff extension. Based on this approach, we report experimental observation of extending the harmonic cutoff energy in Ar to 65  eV with a 400-fold increase in conversion efficiency using a tightly focused truncated Gaussian beam in a short high-pressure gas cell. This new defocusing-assisted phase matching in a highly ionized gas medium can be applied to different targets, laser wavelengths, and pulse durations to extend harmonic upconversion to higher cutoff energy with higher efficiency.

Schematic of the experimental setup for defocusing-assisted phase matching. Operational phase matching is conveniently discovered by tuning the aperture size, together with the focus position with respect to the gas cell, to vary the Δ I / Δ t ratio. See text for more details.

Fig. 2.
Fig. 2.

Comparison of HHG spectrum obtained from three different experimental geometries. It shows that the combination of tight focusing and a short gas cell in (c) gives the highest observed photon energy. Each HHG spectrum in Ar shown here has been fully optimized, aiming for the brightest and highest achievable photon energy by tuning the iris size, backing pressure, and focus position relative to the gas cell. The observed phase-matching cutoff is marked by the inverted purple triangle. With the focal position fixed with respect to the gas cell, (d) and (e) show the HHG spectrum (log scale) versus different iris aperture sizes in the 8- and 0.8-mm-long gas cells, respectively. In (e), a suppression around 51 eV is due to the Cooper minimum of Ar.

Time–frequency analysis of HHG emission from a 10-cycle laser field is shown for the truncated beams of (a)  0.37 W 0 , (b)  0.40 W 0 , and (c)  0.47 W 0 with an 0.8 mm propagation and (d)  0.47 W 0 with an 8 mm propagation in a 50 torr Ar cell. The horizontal line marks the conventional phase-matching cutoff. (e) At 0.47 W 0 , the yield of the 64.7 eV (42.8 eV) harmonic as a function of propagation distance, (f) the electric field at a propagation distance of z = 6    mm and z = 8    mm in the cell, together with the phase-matching zone and the corresponding electron re-scattering trajectories for the 36 eV harmonics, (g) similar plots to (f), but for the off-center position r = 10    μm , z = 0.0 0.4    mm , and for the 60 eV harmonic. These results are obtained by solving the three-dimensional Maxwell’s equations for both the fundamental laser and the high-harmonic field.
