ABSTRACT:
A sintered dense laser block constructed of ceramic metal composition manufactured through sintering, conventional machining and electro discharge machining. A ceramic metal powder and binder are combined and shaped into a laser block. The laser block is then sintered to permit electro-discharge machining. After detailed machining various subsequent firings will yield different dielectric properties for the laser block. Other laser gyro ceramic parts may be manufactured with the method of the invention such as mirror assemblies, cathodes and laser path length controllers. The electro-discharge machining permits the construction of complex ceramic shapes from a slurry of powdered ceramic metal and binder which has been extruded or shaped and then conventional machined. The resulting part is cheaper and easier to make and the electro-discharge machining provides a method of creating very complex shapes in the part.
