COHERENT OPTICAL ARRAY TECHNIQUES.
Abstract
Studies are being conducted to determine the feasibility of a coherent optical phased array system. When fully developed, such a system would not only provide increased beam power concentration on distant targets, but could also conceivably result in electronic beam steering. The over-all plan is to demonstrate feasibility by developing a subassembly consisting of a cw laser master oscillator driving two pulsed laser power amplifiers in parallel. The required phase shifters and power dividers would be incorporated to demonstrate the principles of a coherent optical phased array. The investigation is being conducted for an operating wavelength of 1.06 microns. Solid state and gas lasers are being considered for the master oscillator. Each type has been developed for fully cw operation in the vicinity of 1.06 microns. Solid state crystals have been grown, cut, polished, and coated for amplifier functions of the same wavelength. Gain of several db has been measured. (Author)
