The semiconductor laser apparatus has at least a semiconductor laser array, a collimator lens, a path rotator, and an optical element with a reflecting function. The collimator lens collimates a plurality of laser beams from the semiconductor laser array, in a predetermined direction. The path rotator outputs each beam collimated in the predetermined direction, with a predetermined divergence angle in the predetermined direction in a state in which a transverse section of the beam is rotated by about 90°.

摘要： The present invention relates to a semiconductor laser apparatus capable of reducing a spread angle of an emission light with downsizing. The semiconductor laser apparatus has an active region between a first end surface and a second end surface. A first reflection structure and a partial reflection structure are provided on the first end surface side, and the end surface of the active region is divided into a total reflection region and a partial reflection region in combination with these first reflection structure and partial reflection structure. A laser resonator is constituted by the first reflection structure and partial reflection structure. On the second end surface side, a second reflection structure is provided to be positioned on the way of a resonance optical path of the laser resonator. While the light emitted within the active region propagates on a resonance optical path, an induction emission is produced, and thereby the semiconductor laser carries out a laser oscillation. As a result, among the light arrived at the partial reflection structure, the part having transmitted through the partial reflection structure is outputted outside the semiconductor laser apparatus.

摘要： In this laser beam machine 1, while a pressing portion 9 of an optical guide member 6 presses a lid 13 against a body 12 of a container, the optical guide member 6 annularly guides a laser beam propagated through an optical fiber 4 and outputs it from the pressing portion 9. Thereby, an annular processing region of the body 12 and the lid 13 is entirely irradiated with the laser beam at one time and the lid 13 can be joined to the body 12, whereby improving the working efficiency. Such improvement in working efficiency shortens the processing time and improves the production yield. Furthermore, this laser beam machine 1 does not need to be separately provided with a rotating mechanism for laser beam scanning and a pressurizing mechanism for the body 12 and the lid 13, so that construction of the machine can be significantly simplified.

摘要： An optical condenser device has light sources (10, 20) and an optical combiner (30). Each light source (10, 20) includes a semiconductor laser array stack (12, 22), collimator lenses (16, 26), and beam converters (18, 28). Since the optical combiner (30) combines the beams from one (12) of the stacks and the beams from the other (22), a laser beam with high optical density is generated. The optical combiner (30) has transmitting portions (32) and reflecting portions (34), each of which preferably has a strip-like shape elongated in the layering directions of the stacks (12, 22). In this case, the beams emitted from the active layers (14, 24) will be received and combined appropriately by the optical combiner (30) even if positional deviation of the active layers (14, 24) occurs.
