Abstract:

A new technique for measuring the output power from a cw edge-coupled unstable resonator has been developed and applied to a cw DF laser. An internal-cavity calorimeter was used that permits measurement of output power with a variable rectangular-mode geometry while containing the radiation inside the resonator. The variable aperture calorimeter-absorbing scraper VACAS device consists of an absorbing copper plate calorimeter assembly, which replaces the 45-deg output coupling mirror of a conventional edge-coupled unstable cavity.
