Abstract
A laser has been developed with an active laser element which, in certain aspects, employs no mirrors but instead has a lasant rod with ends formed to produce total or nearly total internal reflection and an output window surface at one end from which a laser beam exits the device. In one aspect a rod end or ends are formed in the shape of polyhedrons whose surfaces reflect oscillating radiation. Also disclosed is a laser with an active laser emitter with a lasant rod with a first end formed in the shape of a polyhedron and a second flat end adjacent to or in contact with a plate or plates of solid reflective, coated or uncoated material, which are next to each other or spaced apart by spacer apparatus, e.g. rings. Such a laser emitter may be used in a laser device without other mirrors or reflectors.
