| Popis: | A helium‐neon maser of the plane parallel Fabry‐Perot type has been constructed in which both the angular adjustments and the plate separation may be controlled through magnetostrictively produced distortion in a rigid Nilvar mounting frame. The maser has been designed with the eventual use of negative feedback frequency stabilization in mind. Orthogonality is maintained in both angular coordinates over a range of about 15″ and the maser has been found to remain within these limits over many days of continuous operation under normal laboratory conditions. Two methods of operation are described : the first permits simultaneous and independent adjustment of both the plate angular alignment and the plate separation. The second method, though requiring less auxiliary equipment, only permits control over the two angular coordinates. Some of the mechanical design considerations and construction details are also discussed. It is felt that the present interferometer design is considerably less susceptible to mechanical instability than others reported to date. |
