摘要： An optical scanning device (32) includes: a light projector (65) configured to radiate light while causing the light to make angular movement at a constant speed; and a light reflector (66) configured to reflect the light radiated from the light projector (65) to guide the light to an intended irradiated point on a predetermined scanning line (52). The light reflector (66) includes a plurality of reflecting portions (71, 72) and reflects, at least twice, the light radiated from the light projector (56) to guide the light to the intended irradiated point. The reflecting portions (71, 72) each include a plurality of reflecting surfaces (77, 78). A length of an optical path from the light projector (65) to the irradiated point is substantially constant for all of irradiated points on the scanning line (52), and a scanning speed, on the scanning line (52), of the light radiated from the light projector (65) is substantially constant.

摘要： A laser processing method includes a preparation step and a processing step. In the preparation step, a workpiece (100), which is a processing object, is set at a processing position. In the processing step, the workpiece (100) set at the processing position is irradiated with pulse laser that has been emitted from a processing head (13) and has passed through an optical scanning device, to form plural holes in the workpiece (100). The optical scanning device scans with the pulse laser, so that a phenomenon in which a position of irradiation with the pulse laser sequentially changes from an initial position to a terminal position at a scanning speed and then returns to the initial position is periodically repeated. In the processing step, a position of irradiating the workpiece with the pulse laser is changed in a direction opposite to scanning with the pulse laser by the optical scanning device and at a speed substantially equal to a speed of the scanning with the pulse laser by the optical scanning device, whereby substantially the same portion of the workpiece (100) is irradiated with the pulse laser corresponding to one period.

摘要： A light guide device includes a plurality of reflection units that reflect incident light so as to guide it to irradiate on an object. The plurality of the reflection units are lined up along a traveling direction of the incident light. Each of the plurality of the reflection units includes a first light guide member that reflects the incident light. Each of the plurality of the reflection units is switched between a reflecting state in which the first light guide member reflects the incident light and a passing state in which the incident light passes through, by rotation of the first light guide member. Timing of being in the reflecting state differs among the plurality of the reflection units. In the reflecting state, the reflected light due to reflection of the incident light is deflected as the first light guide member rotates. The reflected light is led to an irradiated point included in a scanning area in which the reflection unit scans the object to be irradiated. The scanning areas of the plurality of the reflection units are lined up in parallel with the traveling direction of the incident light.

摘要： A polygon mirror rotates around a rotational axis. A first reflection surface and a second reflection surface are placed on two or more of a plurality of sides of the polygon mirror, respectively. The first reflection surface is formed in a planar shape inclined to a plane perpendicular to the rotational axis. The second reflection surface is formed in a planar shape inclined with respect to a plane perpendicular to the rotational axis. Light which entered into the polygon mirror is reflected by the first reflection surface and then by the second reflection surface. Among the plurality of the sides, at least one of a direction in which the first reflection surface is inclined with respect to a plane perpendicular to the rotational axis and a distance in the direction of the rotational axis between the first reflection surface and the second reflection surface is different.
