Claim 0:
1. A data generating device generating data for controlling a spatial light modulator, the data generating device comprising a processor, the processor configured to:
generate an intensity spectrum function A(ω) appropriate for a desired time-intensity waveform;
generate data on the basis of a phase spectrum function Ψ(ω) and the generated intensity spectrum function A(ω);
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;
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;
generate a plurality of objects of the (n+1)-th generation on the basis of the selected two or more objects, wherein transforming the plurality of first waveform functions of the frequency domain into the plurality of second waveform functions of the time domain; calculating the evaluation value; selecting two or more objects; and generating the plurality of objects of the (n+1)-th generation repeat while adding 1 to n until a predetermined condition is satisfied; and
generate 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.
