    • There is provided a light source device having a structure for stably providing a wide-band pulse light having a wavelength spectrum of excellent flatness over a wide band. The light source device uses, as a seed light source, a short-pulse light source having such excellent output pulse characteristic that a frequency band width from the peak to lowered value by 10 dB or 20 dB is 5 THz or above. Furthermore, the light source device includes a wide-band light generation fiber appropriate for combination with such a short-pulse light source. The wide-band light generation fiber inputs a pulse light from a pulse light source and generates a wide-band pulse light by using non-linear optical phenomenon. With this configuration, it is possible to obtain a wide-band pulse light having a wavelength spectrum in which the region having power fluctuation suppressed to 6 dB or below exists over 100 nm or above.
