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.
