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.

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 (12, 22), a collimator lens (16, 26) and a beam converter (18, 28). The optical combiner (30) combines the beams from the light sources (10, 20). The spread of the beams in planes perpendicular to the direction of alignment of the active layers (14, 24) is restrained by the refraction of the collimator lenses (16, 26). The transverse sections of the respective beams are rotated by substantially 90° by the beam converters (18, 28). The spread of the beams in the direction of alignment of the active layers is thus restrained and crossing of adjacent beams becomes unlikely to occur.
