Abstract

A triaxial multioscillator for operation in accordance with a mode of operation requiring the imposition of a substantially uniform axial magnetic field on the gain region of each lasing cavity. An integral frame of glass ceramic material has a rhombic dodecahedral shape and includes three closed lasing cavities, each formed of four straight segments. The cavities include three mutually parallel segments, one from each cavity, that are regularly spaced on a circle perpendicular to the axis of the frame. An internal cathode and six anodes are associated with the frame to provide gain in each of such three segments. The frame is positioned within a closed cylindrical element of soft iron composition by means of a fixture. The fixture positions magnets adjacent the top and bottom of the element to generate parallel lines of magnetic flux therein. The frame is positioned within the container in such a way that the cavity segments containing the three gain regions are aligned with the parallel lines of flux to produce the requisite axial fields in the three gain regions.
