ABSTRACT:
In a solid-state laser device having a laser medium, a reflector member has first and second curved portions surrounding first and second reflector axes, respectively, and an extension portion extended from the first and the second curved portions towards a principal surface of the laser medium for defining an internal space together with the curved portions. Within the internal space, first and second lamps are disposed farther from the principal surface than the first and the second reflector axes, respectively, with first and second lamp axes of the first and the second lamps juxtaposed to the reflector axes and an optical axis of the laser medium. Each curved portion has an arcuate internal surface which forms a partially circular cylinder having a center axis as the reflector axis. Alternatively, the arcuate internal surface of each curved portion forms a partially elliptic cylinder having a symmetry axis as the reflector axis and an outside focal line with which the lamp axis substantially coincides. The extension portion may have a pair of arcuate internal surfaces extended from the arcuate internal surfaces of the first and the second curved portions, respectively. The extension portion may have a pair of parallel internal surfaces.
