摘要： The present invention relates to a fouling removing method which removes a fouling, comprised of a chemical compound containing carbon, on an object surface by laser light irradiation. The fouling removing method irradiates the fouling on the object surface with laser light while blowing a supporting gas on this area. This structure allows the supporting gas and a fouling material to react with each other when burning the fouling by laser irradiation, so as to generate a carbon-containing gas, and the supporting gas to blow away carbonized residues generated on the object surface. This drastically reduces the carbonized residues on the exposed surface of the object having removed the fouling.

摘要： The present invention relates to a laser processing method and the like provided with a structure for enabling realization of both preferable processing of locations not easily reached by laser light and effective inhibition of damage caused to locations easily reached by laser light during laser processing. Radiation optics scan locations irradiated with laser light from a laser light source while radiating laser light onto a plurality of objects arranged on a stage and the periphery thereof from a direction perpendicular to the stage. On the stage reflecting members are respectively arranged adjacent to the plurality of objects. The reflecting members reflect laser light radiated from the radiation optics towards lateral surfaces of the objects. Since laser light reflected by the reflecting members is radiated onto the lateral surfaces of the objects, laser light also reaches the lateral surfaces of the objects not easily reached by laser light without having to increase the intensity of the laser light.

摘要： The present invention relates to a light source apparatus or the like provided with a structure that can block reflected return light also when an emitting end side of an optical isolator is a space. The light source apparatus comprises a light source section, a guide section, and an optical module. The optical module includes a collimator, an optical isolator, and an oblique-beam blocking section. The collimator outputs collimated light with a predetermined beam diameter as a forward propagating beam. The optical isolator is a polarization-independent optical isolator that introduces the collimated light from a first end and outputs this collimated light from a second end. The oblique-beam blocking section includes first and second optical components each having a window of a diameter D, and blocks light incident at a predetermined angle relative to an optical axis of the forward propagating beam out of a backward propagating beam, by separating the first and second optical components from each other by a predetermined distance.

摘要： The invention relates to a light source apparatus having a structure for effectively suppressing a negative effect due to a nonlinear effect generated in propagation of an amplifying light, and realizing a stable operation. In the light source apparatus, light amplified in an optical amplifier fiber is emitted to the outside of the apparatus through an optical output fiber whose one end is connected to an output connecter. At this time, a part of Raman scattered light, generated in the optical output fiber, propagates toward an pumping light source through the optical amplifier fiber from the optical output fiber. An optical component having an insertion loss spectrum that attenuates the Raman scattered light but allows pumping light or light to be amplified to transmit therethrough, is provided on a propagation path of the Raman scattered light, due to the light component, the intensity of the Roman scattered light reaching the pumping light source is effectively reduced. As a result, a negative effect due to a nonlinear effect generated in propagation of light to be amplified can be effectively suppressed, and the light source apparatus can be stably operated.
