Optical pulse train generation device and optical pulse train generation method

An optical pulse train generation device, comprising:

• a storage unit that stores in advance a plurality of phase patterns for forming, from a first optical pulse, an optical pulse train including a plurality of second optical pulses having time differences therebetween and having different center wavelengths, the plurality of phase patterns having different first characteristics regarding the first optical pulse or different second characteristics regarding the optical pulse train or having both of the different first characteristics and the different second characteristics;
• a characteristic setting unit that sets the first characteristic and the second characteristic in response to an input from a user;
• a light source that outputs the first optical pulse;
• and
• a pulse forming unit that has a spatial light modulator that displays one of the plurality of phase patterns and forms the optical pulse train from the first optical pulse,
• wherein the storage unit stores the plurality of phase patterns in association with the first characteristic and the second characteristic, and
• the spatial light modulator displays, among the plurality of phase patterns, one phase pattern corresponding to the first characteristic and the second characteristic set by the characteristic setting unit.
