Abstract: A laser device includes a laser oscillator configured to emit a laser beam, and an optical unit configured to receive the laser beam and emit the laser beam outside. The optical unit includes: a partially transmissive mirror configured to reflect a part of the laser beam toward the outside and transmit a remaining part of the laser beam; a diffusion plate configured to diffuse the laser beam which has passed through the partially transmissive mirror and deflect the laser beam in a predetermined direction, at a predetermined diffusion angle; and a photodiode configured to receive the laser beam deflected by the diffusion plate, and output an electric signal. The laser device is configured such that deviation of an optical axis of the laser beam is monitored based on the electric signal of the photodiode.

Abstract: A laser processing head includes parallel plate (17) that shifts an optical axis of a laser beam to be emitted from a top to a bottom of body case (6) from a first optical axis to a second optical axis, parallel plate (19) that shift the optical axis of the laser beam from the second optical axis to a third optical axis, and body case (6) that accommodates holders (7 and 18) that respectively hold parallel plates (17 and 19). The laser processing head further includes a rotation mechanism that rotates holders (7 and 18) around a first rotary axis. Opening (7a) that a laser beam reflected by an incident surface of second parallel plate (19) passes through is formed in holder (7), and light receiving part (6a) that receives the laser beam having passed through opening (7a) is disposed in body case (6).

Abstract: A condenser lens for collecting a laser beam (300) is disposed between the laser oscillator and the incident end surface of the optical fiber. The laser beam (300) is divided into a plurality of beams (303, 304). The power of the laser beam (304) is measured and maximized by adjusting the position of the condenser lens. The FFP of the laser beam (303) is measured and minimized by adjusting the position of the condenser lens. These adjusted positions are stored as the first and second lens positions. The FFP of the laser beam (303) is measured while the condenser lens is being moved between these positions so as to make the BPP not more than a predetermined value.

Abstract: An apparatus management device includes a display unit, an operation unit, a storage unit, a selection unit, and an apparatus control unit. The storage unit stores a correspondence relationship between a user request, an apparatus, and a control condition. The control condition is a condition for the apparatus to be in an operating state appropriate for the user request. The operation unit receives an input operation of the user request. The selection unit selects an apparatus that does not satisfy the control condition from apparatuses that are associated, in the correspondence relationship stored in the storage unit, with the user request accepted by the operation unit. The display unit displays the apparatus selected by the selection unit.

Abstract: There is provided an optical axis alignment mechanism between the laser oscillator and the optical fiber. The laser oscillator emits laser light, which then emerges from the emission end of the optical fiber via the axis alignment mechanism. Part of the laser light is received on the light-receiving surface of the CCD camera of a laser light evaluator. Thus, the laser light evaluator acquires a light intensity distribution. The light intensity distribution is used by the optical axis alignment mechanism to align the axis of the laser oscillator with the axis of the optical fiber.

Abstract: A fiber coupling device (100) includes the following components: a wedge plate (102) for receiving light and refracting the light in a predetermined direction, a condenser lens (104) for collecting the light refracted by the wedge plate (102); and an optical fiber (107) having an incident surface for receiving the light collected by the condenser lens (104). The wedge plate (102) is held rotatable around the optical axis (200) of the light incident on the wedge plate (102). The light refracted by the wedge plate (102) and collected by the condenser lens (104) is incident on a different point on the incident surface depending on the rotation angle of the wedge plate (102).
