Abstract
Resonant cavity apparatus comprise a Fabry-Perot optical resonant cavity of a type having families of transverse modes between longitudinal TEM.sub.00 modes. In such resonant cavity apparatus and in methods of minimizing the effect of transverse modes, families of such transverse modes are merged into longitudinal TEM.sub.00 modes of the non-confocal Fabry-Perot optical resonant cavity, providing superior optical performance. This may be manifested by a transmission spectrum similar to that of a flat-flat Fabry-Perot cavity, but with superior Finesse and transmission efficiency.
