MASER FOR FREQUENCIES IN THE 7{14 20 GHz RANGE

摘要

A traveling wave maser (TWM) of the comb type is disclosed for operation in the 7-20 GHz frequency range. The TWM is loaded with 0-degree Czochralski grown ruby with its C-axis at angle theta =90 DEG with respect to the magnetic field. The TWM is pumped in the push-push mode between levels 1-3 and 3-4 with two different frequencies.
