Claim 11:
12. A method of generating data for controlling a spatial light modulator, the method comprising:
generating an intensity spectrum function A(ω) and a phase spectrum function Ψ(ω) appropriate for an optical pulse train including a plurality of optical pulses aligned with a time interval left therebetween; and
generating the data on the basis of the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω),
wherein generating of the spectrum function includes:
setting a plurality of object pairs of a first generation relating to the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω);
calculating an evaluation value representing an amount of loss occurring due to intensity spectrum modulation based on a plurality of objects of an n-th generation (here, n is an integer that is equal to or greater than “1”) of the intensity spectrum function A(ω) for each object pair;
selecting two or more object pairs used for generating a plurality of object pairs of an (n+1)-th generation among a plurality of object pairs of the n-th generation on the basis of superiority of the evaluation value; and
generating a plurality of object pairs of the (n+1)-th generation on the basis of the two or more object pairs,
wherein calculating of the evaluation value, selecting of the object pairs, and generating of the object pairs are repeated while adding 1 to n until a predetermined condition is satisfied, and, in generating of the spectrum function, the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω) that are appropriate for the optical pulse train are generated from a plurality of object pairs of an n-th generation of a case in which the evaluation value satisfies a predetermined condition.
