PROBLEM TO BE SOLVED: To realize a laser light source apparatus which outputs laser beams having two wavelengths switching on an optical axis to high speed. SOLUTION: The laser light source apparatus is characterized by that the laser light source apparatus has a light source means which simultaneously outputs two different wavelengths, a first optical system which forms a first and a second optical axes by separating a light beam from the light source means into respective wavelengths, a light shielding means which shields one or both of the first and the second optical axes by means of a rotating chopper plate, and a second optical system which fits the light beams of the first and the second optical axes onto one and the same emitting optical axis, and outputs a plurality of discontinuous wavelengths sequentially switching.
