ABSTRACT:
The present invention relates to a light source apparatus having a structure for stably supplying broadband pulsed light having a wavelength spectrum with an excellent flatness over a wide band. The light source apparatus employs, as a seed light source, a short-pulsed light source having such an excellent output pulse characteristic that the frequency bandwidth extending until the output pulse drops by 10 dB or 20 dB from a peak is 5 THz or more. The light source apparatus also includes a broadband light producing fiber having an optical characteristic suitable for combining with the short-pulsed light source. The broadband light producing fiber inputs pulsed light from the pulsed light source, and produces the broadband pulsed light by utilizing a nonlinear optical phenomenon. This structure yields broadband pulsed light having such a wavelength spectrum that a region whose power fluctuation is suppressed to 6 dB or less extends over 100 nm or more.
