A light source includes: a light source system includes: a light source unit producing a first pulsed light beam having a plurality of frequency components; a splitter splitting the first pulsed light beam into second and third pulsed light beams; a first photonic crystal fiber converting the split second pulsed light beam into a wider bandwidth; a second photonic crystal fiber converting the split third pulsed light beam into a wider bandwidth; a first adjuster adjusting a spectrum of the second pulsed light beam converted into the wider bandwidth; a phase adjuster matching phases of the second and third pulsed light beams converted into the wider bandwidth; and a superimposing unit superimposing the second pulsed light beam having the adjusted spectrum and the third pulsed light beam converted into the wider bandwidth.
