Using high-power nanosecond pulses, we measured the second-harmonic conversion efficiency of two-dimensional hexagonally poled lithium niobate as a function of temperature and wavelength. These results were compared with theoretical estimates and with measurements in one-dimensional periodically poled lithium niobate. We found that for a substantial range of parameters a two-dimensional noncollinear interaction has a broader tuning response than a one-dimensional collinear interaction. We also observed and characterized third- and fourth-harmonic generation processes in the same crystal.

  17. One can, of course, design crystals in which any desired Fourier coefficients are maximized; however, such crystals are likely to contain fine features that are not easily fabricated. Our decision to look only at low-order Fourier components is based on the fact that the resultant patterns are easily fabricated.
