Beschreibung
Zusammenfassung:	A laser light-source apparatus includes: fiber amplifiers and a solid state amplifier configured to amplify pulse light output from a seed light source based on gain switching; nonlinear optical elements configured to perform wavelength conversion on the pulse light output from the solid state amplifier; an optical switching element configured to permit or stop propagation of pulse light from the fiber amplifier to the solid state amplifier; and a control unit configured to control the optical switching element in such a manner that the propagation of the light is stopped in an output period of the pulse light from the seed light source, and permitted in a period other than the output period of the pulse light from the seed light source.
