In a solid-state laser device comprising a laser oscillation medium and a laser amplification medium, a reflector member has an internal wall surface defining a single prismal space in which both of the oscillation and the amplification media are placed. A flash lamp is intermediate between the oscillation and the amplification media in the prismal space to activate both media in common. The oscillation and the amplification media are of a rod type and a slab-type, respectively. Preferably, the prismal space is divisible into an elliptic cylinder space having in cross section two ellipse focal points and a parabolic cylinder space having in cross section a parabola focal point common to one of the ellipse focal points. The oscillation medium is placed on another one of the ellipse focal points while the flash lamp is placed on the parabolic cylinder space and interposed between the oscillation and the amplification media. An additional oscillation medium may be placed in an additional parabolic cylinder space opposite to the parabolic cylinder space relative to the amplification medium. Alternatively, disposition of a plurality of oscillation media may be symmetrical with respect to the amplification medium in the prismal space with flash lamps interposed between the oscillation media and the amplification medium.
