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.

摘要： A semiconductor laser device 3 includes an n-type clad layer 13, an active layer 15, and a p-type clad layer 17. The p-type clad layer 17 has a ridge portion 9 that forms a waveguide 4 in the active layer 15. The waveguide 4 extends along a central axial line B that is curved at a substantially constant curvature (curvature radius R). In such a waveguide 4, of the light components that resonate inside the waveguide 4, light components of higher spatial transverse mode order are greater in loss. Laser oscillations of high-order transverse modes can thus be suppressed while maintaining laser oscillations of low-order transverse modes. A semiconductor laser device and a semiconductor laser device array, which can emit laser light of comparatively high intensity and with which high-order transverse modes can be suppressed, are thereby realized.

摘要翻译： 半导体激光器件3包括n型覆盖层13，有源层15和p型覆盖层17。 p型覆盖层17具有在有源层15中形成波导4的脊部9。 波导4沿着基本上恒定曲率（曲率半径R）弯曲的中心轴线B延伸。 在这样的波导管4中，在波导4内谐振的光分量中，空间横向模式次序的光分量的损耗更大。 因此可以抑制高阶横模的激光振荡，同时保持低阶横模的激光振荡。 由此，可以实现能够发出较高强度的高光束和可以抑制高阶横模的半导体激光器件和半导体激光器件阵列。

摘要： The present invention relates to a semiconductor laser element and the like which can efficiently emit laser beams at a small emission angle using a simpler configuration. The semiconductor laser element has a structure where an n-type cladding layer, active layer and p-type cladding layer are sequentially laminated. The p-type cladding layer has a ridge portion for forming a refractive index type waveguide in the active layer. The ridge portion, at least the portion excluding the edges, extends in a direction crossing each normal line of both end faces of the refractive index type waveguide, which corresponds to the light emitting face and light reflecting face respectively, at an angle θ, which is equal to or less than the complementary angle θc of the total reflection critical angle on the side face of the refractive index type waveguide. The optical paths of light components which resonate in the refractive index type waveguide formed by the ridge portion having the above form are limited to optical paths where the lights are totally reflected on the side face of the refractive index type waveguide. In other words, the laser beams emitted from the light emitting end have a spatial horizontal single mode, and the waveguide width can be increased to further decrease the emission angle of the laser beams.

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： In the first period from pumping start time T1 to time T2 in a laser light source 1, the power of pumping light L1 outputted from a pumping light source 41 so as to irradiate a laser medium 21 is at value P1 whereas the power of light L2 incident on a saturable absorber 30 after being emitted from the laser medium 21 is at an absorption saturation threshold or lower, which causes a resonator 10 to lower its Q-value, thereby suppressing the laser oscillation. Immediately before time T2, the power of light L2 is slightly lower than the absorption saturation threshold. In the second period subsequent to the first period, the power of light L2 is at value P2 greater than the above-mentioned value P1, whereas the power of light L2 exceeds the absorption saturation threshold, which causes the resonator 10 to increase its Q-value, whereby a mirror 12 outputs pulse laser light L3 to the outside.
