Abstract: A plasma light source apparatus includes a first laser generator configured to generate a first laser. A second laser generator is configured to generate a second laser. A chamber is configured to accommodate and seal a medium material for plasma ignition and to allow plasma to be ignited by the first laser and to be maintained by the second laser. An inner surface of the chamber includes two curved mirrors that face each other.

Abstract: A method of inspecting a surface of an object includes providing a laser beam irradiated in a first direction substantially parallel to the surface of the object, adjusting a diameter of the annular laser beam, reflecting the annular laser beam toward the surface of the object in a second direction substantially perpendicular to the first direction, in a primary reflection, and reflecting the primarily reflected laser toward an inspection region of the object, in a secondary reflection. An incident angle of the annular laser beam with respect to the surface of the object may be determined by the diameter of the annular laser beam.

Abstract: A plasma light source apparatus is provided. The plasma light source apparatus includes a chamber, a laser generating part, and a curved mirror. The chamber includes a plasma source gas for generating laser induced plasma. The laser generating part is spaced apart from the chamber and generates a hollow laser beam. The curved mirror is disposed between the chamber and the laser generating part. The curved mirror is configured to reflect and to condense the generated hollow laser beam into the chamber to generate the laser induced plasma in the chamber, and to reflect light emitted from the generated laser induced plasma.
