Claim 10:
11. A method of generating data for controlling a spatial light modulator, the method comprising:
generating an intensity spectrum function A(ω) appropriate for a desired time-intensity waveform; and
generating the data on the basis of a phase spectrum function Ψ(ω) and the intensity spectrum function A(ω),
wherein generating of the intensity spectrum function includes:
setting a plurality of objects of a first generation of the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω);
transforming 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 calculating 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;
selecting 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 the evaluation value; and
generating a plurality of objects of the (n+1)-th generation on the basis of the two or more objects, and
wherein calculating of the evaluation value, selecting of the objects, and generating of the objects are repeated while adding 1 to n until a predetermined condition is satisfied, and, in generating of the intensity spectrum function, an intensity spectrum function A(ω) that is appropriate for the desired time-intensity waveform is generated from a plurality of objects of the n-th generation of a case in which the predetermined condition is satisfied.
