ABSTRACT

Optical resonateors and regenarative laser amplifiers are disclosed. In all cases, the resonateors are made fully degenerate, in order to be useful in processing multiple modes or amplifying images. Full degeneracy is accomplished with relatively few lenses by inverting any bundle of resonated rays at planar reflectors. The resonators typically employ one or more rooftop reflectors or corner reflectors arranged to provide ray inversion.
