Claim Text:
1. A pulse shaping device comprising: a pulse generator configured to generate pulsed light by using a semiconductor laser for emitting light of a predetermined wavelength; an optical member provided in a subsequent stage of the pulse generator, the optical member configured such that the generated pulsed light propagating in a forward direction of the x-axis is incident on the optical member, and the optical member is configured to compress a pulse time width of the pulsed light; and a mirror disposed in a subsequent stage of the optical member and configured to reflect the generated pulsed light from the optical member such that the reflected light from the mirror propagates through an inside of the optical member, wherein the pulsed light has a first frequency dispersion state, and wherein the optical member imparts a second frequency dispersion state to the pulsed light, the second frequency dispersion state being a frequency dispersion state opposite to the first frequency dispersion state.
