摘要： The present invention relates to a laser marking method which is capable of changing the grey level of a marking even in the case of a high processing speed. The laser marking method forms a marking pattern on a marking object by irradiating the marking object with pulsed light oscillated from a pulsed light source of a MOPA structure in which a semiconductor laser outputting directly-modulated pulsed light is used as a seed light source. At this time, the pulse duration of the pulsed light is changed in order to change a gray level of the marking pattern to be formed. In this way, a peak power of the pulsed light is changed by changing the pulse duration, so that it is possible to positively change the gray level of the marking pattern without changing the processing speed.

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.

摘要： The present invention relates to a laser light source having a structure for narrowing a wavelength bandwidth of output light. The laser light source comprises, at least, a laser resonator, a pumping light source, an optical path switch device, a diffraction grating, and a total reflection mirror. The laser resonator has a light amplifying fiber for output of emission light arranged on a resonance optical path thereof.

摘要： The present invention relates to a laser light source having a structure that has high durability to support high power output. The laser light source is an optical device that pulse-oscillates laser light and has a resonator, a rare earth element doped fiber, pumping means, Q switch means, and a condensing lens. The resonator forms a resonance optical path. A fiber is inserted on the resonance optical path and outputs radiation light by supply of pumping energy. The pumping means continuously supplies pumping energy to the fiber. The Q switch means modulates resonator loss of the resonator. The condensing lens condenses the radiation light whose spot size has been expanded and which propagates from the fiber to the Q switch means. The Q switch means is disposed such that a portion contributing to at least a resonator loss modulation is located at the condensing point of radiation light which is condensed by the condensing lens, and mechanically changes formation and interruption of the resonance optical path by transmitting or interrupting the radiation light in the contributing portion.

摘要： The present invention relates to a laser welding method of welding an electrode and a cable core to each other satisfactory by irradiation of a laser beam, even when the core is thin and the area of the electrode is small. The laser welding method welds on a substrate the electrode and the core of a coaxial cable to each other by irradiation of the laser beam. The core is sandwiched between a pressing member and the electrode, while the electrode and the core are brought into contact with each other at a connection section. The pressing member is a member that is transparent to the processing laser beam. A part of the core is molten by radiating the laser beam from the pressing member side. As a result, the electrode and the core are connected with each other.
