1. A light shaping device comprising:
an intensity modulator configured to modulate a spectrum intensity of an optical pulse that is input light, and to output the optical pulse of which a temporal width is narrowed as output light,
wherein the intensity modulator modulates the spectrum intensity of the input light with a mask expressed by a starting end wavelength λr and a wavelength width W from the starting end wavelength λr, and
wherein a transmittance of the input light in a wavelength region of which an intensity is modulated with the mask is 10% or less.
