摘要： A solid-state laser apparatus which can cool a solid-state laser medium such that the solid-state laser medium attains a uniform temperature along the propagating direction of light to be amplified is provided. In a solid-state laser apparatus 1, a coolant circulating through flow paths 12a, 12b comes into direct contact with a pair of reflecting end faces 5a, 5b of a solid-state laser medium 3, whereby the laser medium 3 heated by pumping light emitted from semiconductor lasers 9 can efficiently be cooled. Since the coolant circulates through the flow paths 12a, 12b in a direction substantially perpendicular to a propagating surface P of light to be amplified L, the solid-state laser medium 3 can be cooled such as to attain a uniform temperature along a propagating direction of the light L. This can lower the thermal lens effect and thermal birefringence effect in the solid-state laser medium 3.

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.
