Abstract
An internal cavity calorimeter for measuring the output power from an edge coupled unstable laser resonator with a variable rectangular mode geometry while containing the radiation inside the resonator. The 45.degree. output coupling mirror of a conventional edge coupled unstable cavity is replaced by a calorimeter assembly including an absorbing copper plate having a rectangular hole of variable width w and height h to define a rectangular mode of variable width Mw and height Mh within the geometric optics approximation where M is the magnification.
