Claim 15:
16. A data generating device generating data for controlling a spatial light modulator, the device comprising circuitry configured to:
generate an intensity spectrum function A(ω) and a phase spectrum function Ψ(ω) for an optical pulse train including a plurality of optical pulses aligned with a time interval left therebetween;
generate the data on the basis of the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω);
set a plurality of object pairs of a first generation relating to the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω);
calculate 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;
select 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 generate a plurality of object pairs of the (n+1)-th generation on the basis of the two or more object pairs,
wherein the circuitry repeats calculation of the evaluation value, selecting of the object pairs, and generating of the object pairs while adding 1 to n until a predetermined condition is satisfied, and in designing of the intensity spectrum, generates the intensity spectrum function A(ω) and the phase spectrum function Ψ(ω) for generating the optical pulse train from a plurality of object pairs of an n-th generation of a case in which a predetermined condition is satisfied.
