The present invention is concerned with providing an apparatus for measuring the output power from an edge coupled unstable resonator as a function of mode geometry without fabrication of a variety of coupling mirrors and without the need for a window. The apparatus includes a flat absorbing metal plate positioned perpendicular to the optical axis of the resonator and replacing the output coupling mirror therein. A rectangular hole in the plate is centered with and orthogonal to the cavity output power while containing the radiation within the cavity.
