Interferometric power amplifiers.
A general method of producing multielement amplifiers having a single output beam is described. The basic building blocks for these are either Michelson interferometers or Mach-Zehnder interferometers modified by the inclusion of gain in at least one arm of the interferometer. Demonstration of these multielement interferometric power amplifiers using broad-area AlGaAs gain elements and a single-mode AlGaAs master oscillator is described.
