Abstract
A laser light source apparatus includes a compound cavity and an optical gain medium. The compound cavity includes first, second, and third optical reflection members disposed along the optical axis. The first optical reflection member has a light wavelength selectivity. At least one of the first to third optical reflection members can change its own position on an optical axis in relation to the other reflection members. Two of the first to third optical reflection members are provided opposite to each other with the optical gain medium inserted therebetween, thereby forming a laser light source. The other one optical reflection member is provided so as to form a light path for feeding laser light emitted from the laser light source back to the laser light source.
