Beschreibung
Zusammenfassung:	A laser light-source apparatus includes: a fiber amplifier and a solid-state amplifier configured to amplify pulse light output from a seed light source serving as a first light source; a nonlinear optical element 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 the pulse light from the fiber amplifier to the solid-state amplifier; a second light source that is disposed on an upstream side of the solid-state amplifier and is configured to output laser light that is able to be combined with the pulse light output from the seed light source; and a control unit configured to control the optical switching element in such a manner that the propagation of light is stopped and to perform control in such a manner that the second light source oscillates, at least in an output period of the pulse light from the seed light source.
