Title: Maser amplifiers
IPC: H01S1/02
Filed: 1976-01-22
Abstract: 1493765 Masers NATIONAL AERONAUTICS & SPACE ADMINISTRATION 22 Jan 1976 [12 Feb 1975] 02435/76 Heading H1C Signals 27, Fig. 2, to be amplified are applied at one end of a waveguide 17 containing a slow wave, maser structure 21, and are reflected by mismatch at the other waveguide end 23 so as to effect two amplifying passes through the maser material, the signal input and output put channels 13, 35 being segregated by a circulator 15. The maser material may be ruby which is pumped through the waveguide end 23 from a source 81, the maser material filling the waveguide and having its ends tapered to match with the waveguide impedance. The operational band width of the amplifier is determined by the non-uniformity of a magnetic field produced between non-parallel pole faces 83, 85 of a superconducting or alnico magnet. A plurality of amplifying stages are shown, each comprising a waveguide 45, 65 coupled to the circulator of the preceding stage by a respective circulator 43, 63 and an isolator 37 formed by a circulator with a loaded port, Fig. 3 (not shown). The non-uniform magnetic field may alternatively be produced between parallel pole faces 161, 163, Fig. 6, by including high permeability ferromagnetic slabs 167-173 in the field 165, or by the use of energized coils 191-195, Fig. 7, each embracing a portion of the field 197. In the latter case the band width is controllably determined by adjusting the intensity and direction of the field produced by each coil. A comb-like slow wave maser structure may alternatively be used, two such structures mounted in respective portions of a double waveguide 123 being shown in Fig. 4. Each structure consists of two slabs 139, 141 of maser material pressed by a spring device 145 against an intermediate comb formed by metallic fingers 143. Although waveguide connecting channels are primarily used, the use of coaxial cables coupled to waveguide 17 is disclosed, Fig. 5 (not shown). The amplifier operates at cryogenic temperature.
