Abstract
A laser light-source apparatus includes: a seed light source; a fiber amplifier configured to amplify pulse light output from the seed light source based on gain switching; a solid state amplifier configured to further amplify the resultant pulse light; a nonlinear optical element configured to perform wavelength conversion on the pulse light output from the solid state amplifier; an optical switching element that is disposed between the fiber amplifier and the solid state amplifier and is configured to remove ASE noise; and a control unit. The control unit is configured to control the optical switching element in such a manner that propagation of light is permitted in an output period of the pulse light from the seed light source, and is stopped in a period other than the output period.
