Abstract
In an optical amplifying section that includes a specific amplifying medium that may be effected by a giant pulse, light subject to amplifying is continuously incoming, while exciting light is continuously supplied. Therefore, in the specific amplifying medium, the giant pulse is not generated, which allows continuous amplified light to be emitted stably from the specific amplifying medium. Meanwhile, of the light outgoing from the optical amplifying section, a light quantity controlling section controls the light quantity of light proceeding a predetermined optical path to a wavelength conversion section, which controls the light quantity of light outgoing from wavelength conversion section as outgoing light of the light source unit. As a consequence, light with high luminance whose wavelength has been converted can be stably emitted.
