Abstract
This invention provides a pulse shaping technique that can yield a pulsed laser having a smaller energy fluctuation than that of a conventional pulse shaping technique using one or two non-linear optical crystals. A pulse shaping device includes: a non-linear optical crystal group including at least three non-linear optical crystals arranged side by side on an optical path of an input pulsed laser.
