A laser light source apparatus includes: a laser light source 1 that emits a laser beam; a condenser lens 2 that converges the laser beam emitted from the laser light source 1; and a light guide unit 3 that propagates and outputs the laser beam converged by the condenser lens 2, and the laser beam converged by the condenser lens 2 is made incident at an angle other than perpendicular to an incident end face of the light guide unit 3. |
