ABSTRACT:
A compact RF excited annular laser system has a stable resonator with a high quality output beam. The stable resonator has internal axiconical and annular mirrors to conform with the annular lasing medium, and to convert the annular beam into a compact cylindrical beam. Mode control is achieved by a combination of diffractive effects in both the annular beam and the compact beam.
