Abstract:
A laser light source apparatus includes: a laser light source that emits a laser beam; a condenser lens that converges the laser beam emitted from the laser light source; and a light guide unit that propagates and outputs the laser beam converged by the condenser lens, and the laser beam converged by the condenser lens is made incident at an angle other than perpendicular to an incident end face of the light guide unit.
