Document Type and Number:
WIPO Patent Application WO/2018/042983
Kind Code:
A1
Abstract:
In the present invention, a Fourier transform is performed on a first waveform function in a frequency region including an intensity spectrum function and a phase spectrum function, and a second waveform function in a time region including a time-intensity waveform function and a time-phase waveform function is generated. Substitution of a time-intensity waveform function based on a desired waveform is performed for the second waveform function. The second waveform function is corrected so that a spectrogram of the second waveform function approaches a target spectrogram generated in advance in accordance with a desired wavelength band. An inverse Fourier transform is performed on the corrected second waveform function, and a third waveform function in the frequency region is generated. Data are generated on the basis of an intensity spectrum function or a phase spectrum function of the third waveform function. The wavelength component (frequency component) of light constituting the time-intensity waveform can thereby be controlled.
