Abstract: A modulation pattern calculation apparatus includes an iterative Fourier transform unit, a filtering process unit, and a modulation pattern calculation unit. The iterative Fourier transform unit performs a Fourier transform on a waveform function including an intensity spectrum function and a phase spectrum function, performs a replacement of a temporal intensity waveform function based on a desired waveform after the Fourier transform and then performs an inverse Fourier transform, and performs a replacement to constrain the phase spectrum function after the inverse Fourier transform. The filtering process unit performs a filtering process of cutting a part exceeding a cutoff intensity for each wavelength, on the intensity spectrum function in a frequency domain.

Abstract: A wavelength conversion element includes a crystal having a periodically poled structure in which polarization is inverted with an inversion period Λ along a z-axis which is an input axis of a light pulse. The wavelength conversion element is configured to generate an output light pulse converted to have an output frequency f(x) corresponding to the inversion period Λ(x) at each position x by change of the inversion period Λ according to the position x, and when a target frequency linearly changing with the position x is set to fT(x)=b+ax, a frequency width of the output frequency is set to δf(x), and the output frequency is set to f(x)=fT(x)+α(x), the output frequency is set to coincide with the target frequency within a range satisfying a condition |α(x)|≦δf(x).
