Abstract: Deflection of laser beams, irrespective as to whether this is implemented within or externally of the laser itself; necessitating the utilization of metal mirrors or reflectors of high-quality which, in short, are designated as laser mirrors or reflectors. Laser mirrors of that type require an extremely good mirror surface, a high reflective capability and a good geometric planicity, as well as a high surface hardness. Brass possessing an inherently known microduplex matrix or grain structure provides a significant improvement in the properties of laser mirrors. A material of that type has, by nature, a microcrystalline structure, possesses a freedom from stresses, a high degree of stiffness, and a good material hardness.

Abstract: An explosive charge with a projectile-forming metallic insert which, essentially, possesses the configuration of a spherically-curved dish. The insert should be constituted of a body from a single-crystal. Pursuant to a modification, in an explosive charge of the above-mentioned type which additionally possesses a member for the guidance or deflection of the detonation waves, it is contemplated that this member be also constituted from a single-crystal.

Abstract: A penetrator which is constituted of a heavy-metal, for example, a metal such as tungsten or depleted uranium, and which possesses a differently designed tensile strength and ductility along its length; and a method of manufacturing the penetrator. The penetrator is constituted of a single-crystal of the heavy-metal. The penetrator can be constituted from tungsten; however, it can also be constituted of an alloy whose main component is tungsten, to which rhenium is alloyed.

Abstract: A deformable mirror, especially for the compensation of the influences of atmospheric interferences on the propagation or spreading of high energy laser beams, which incorporates a plurality of electrically actuatable actuators or adjusting elements engaging behind the mirror surface of the mirror. The actuators or adjusting elements is pressed against the rear side of a mirror plate, and is connected therewith along jacket or sheathing surfaces. Thereby, it is possible to achieve an almost point-like introduction of force for the regional deformation of the mirror; inasmuch as the pressure forces can act with a practically randomly small cross-section directly against the rear side of the mirror, while the tensile forces are taken up by the jacket or sheathing surfaces.
