10. 6 micron parametric frequency converter. Semiannual technical report, 1 Sep 1974-28 Feb 1975
This program addresses an approach which should lead to a new class of electro-optical devices such as single sideband modulators, tunable local oscillators, and frequency shifters, using the resonant interaction of optical and microwave fields in a gas whose energy level structure is controlled by an applied electric field (Stark effect). The molecule NH/sub 2/D has an infrared absorption line which may be tuned into resonance with the P(20) 10.6 micrometer CO/sub 2/ laser transition by application of an electric field. The authors exploited this interaction to frequency stabilize a gigahertz tunable waveguide CO/sub 2/ laser, demonstrating precise control of the waveguide laser frequency over a bandwidth greater than 1 GHz, and solving one of the major problems in CO/sub 2/ laser frequency control. The experience with these interactions in stark tunable molecules has stimulated the concepts and ideas which are being implemented in this program.
