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 present invention relates to a laser processing apparatus having a structure for effectively processing of objects by condensing a laser beam, and a laser processing method. A laser processing apparatus comprises a common mount surface on which plural objects are disposed in an array, a light source, a lens the reflection direction of which is changeable, and a condensing direction modifier. A laser beam from the light source arrives at the lens through a galvano-mirror. Herein, the galvano-mirror is arranged such that the reflection position thereof agrees with the front focal position of the lens. As the galvano-mirror reflects a laser beam toward the lens while the reflection direction is changed, the arriving position of the laser beam is scanned on the entrance surface of the lens. The condensing direction modifier modifies, according to the irradiation position of the laser beam arrived from the lens, an exit direction of the laser beam.

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.
