Claim 14:
15. A data generating device generating data for controlling a spatial light modulator, the data generating device comprising circuitry configured to:
generate an intensity spectrum function A(ω) appropriate for a desired time-intensity waveform;
generate the data on the basis of a phase spectrum function Ψ(ω) and the intensity spectrum function A(ω) generated;
set a plurality of objects of a first generation of the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω);
transform a plurality of first waveform functions of a frequency domain including a plurality of objects of an n-th generation (here, n is an integer equal to or greater than “1”) and the phase spectrum function Ψ(ω) into a plurality of second waveform functions of a time domain each including a time-intensity waveform function and a time-phase waveform function and calculate an evaluation value representing a degree of difference between the time-intensity waveform function and the desired time-intensity waveform for each of the second waveform functions;
select two or more objects used for generating a plurality of objects of an (n+1)-th generation among a plurality of objects of the n-th generation on the basis of superiority of the evaluation value; and
generate a plurality of objects of the (n+1)-th generation on the basis of the two or more objects, and
wherein the circuitry repeats calculation of the evaluation value, selecting of the objects, and generating of the objects while adding 1 to n until a predetermined condition is satisfied, and in designing of the intensity spectrum, generates an intensity spectrum function A(ω) appropriate for the desired time-intensity waveform from a plurality of objects of the n-th generation of a case in which the predetermined condition is satisfied.
