摘要： A slab module for a face-pumped laser includes a box frame having top and bottom walls and opposite end walls defining a central slab chamber therein. The end walls have central access holes for receiving opposite ends of a laser slab positionable in the slab chamber. The frame also includes opposite side pockets which join with the slab chamber. The pockets are configured for receiving laser pumping modules for pumping the laser slab, with the modules including diode laser arrays in an exemplary embodiment.

摘要： A passive Q-switch element is disclosed that permits operating a laser with a variable pulse repetition frequency (PRF). The Q-switch comprises two wedges of material, one made from saturable absorber material, the other from transparent material, with the two wedges mounted together to form a constant optical thickness block. By translating the block transversely to a laser beam the amount of saturable absorber material seen by the laser beam is altered and as a result the PRF of the laser is varied.

摘要： 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.
