Claim 0:
1. An optical pulse pair generator configured to generate an optical pulse pair including a first pulse beam and a second pulse beam having respective central wavelengths that are separated by a predetermined wavelength difference from each other and having target time waveforms that are substantially the same as each other, the optical pulse pair generator comprising:
a splitter section configured to split an incident pulse beam into two;
a first shaping section configured to shape one of the pulse beams split by the splitter section by shaping into the target time waveform and setting a central frequency so as to configure the first pulse beam; and
a second shaping section configured to shape the other of the pulse beams split by the splitter section by shaping into the target time waveform so as to configure the second pulse beam,
wherein the first pulse beam and the second pulse beam both have an asymmetric waveform with a fall time that is longer than a rise time, and are temporally superimposed on each other.
