Abstract
A laser device having an improved resonator utilizes a single rigid base component for a light reflector coating that defines and forms the end terminals of the resonator cavity, means being provided for translating and reflecting the laser beam between linear light paths that respectively terminate at the mirror surfaces provided by the coating. Various embodiments are shown and in which one or more prisms are used to fold the laser beam between offset and parallel light paths. The end terminal forming mirror surfaces may be coplanar and face in a common direction in the base component, or the mirror surfaces may be provided on opposite side surfaces of the component. Where the base component is made from transparent material the terminals may also be defined by the inside and outside surfaces of the coating. The use of figured surfaces in the unitary structure is contemplated and the use of mirror clusters for folding the beam is also contemplated. The rigid base component may be provided by a prism, a solid state laser rod, the envelope for a fluid lasing medium or any suitable rigid unitary structure that has an appropriate surfaces arrangement for the contemplated use.
