Abstract
A light source apparatus comprises one laser oscillator, at least one other laser oscillator, a light converter for converting a laser beam emitted from the other laser oscillator into a ring-shaped laser beam, and a reflecting mirror for passing a laser light beam emitted from the one laser oscillator through the center hole of the mirror and for reflecting the ring-shaped laser beam from the other laser oscillator via the light converter, the laser beam reflected by the reflecting mirror being coaxial with and being overlapped with the laser beam transmitted through the mirror from the one laser oscillator.
