ABSTRACT:
In a slab laser, the optical pumping lamps extend transversely to the mean direction of the laser beam with the spatial period of the lamps being harmonically related to the spatial period of the zig-zag laser beam path within the slab, preferably with equal periods. In addition, the lamps are preferably positioned in registration over the lines of intersection of the central ray of the laser beam with respective broad face of the laser slab. A planar flashlamp reflector is employed for economy of fabrication. Directional lamp reflectors are employed for increasing laser efficiency and performance by discriminating against amplified surface waves.
