ULTRAVIOLET TRANSMITTER DESIGN AND DEVELOPMENT PROGRAM
Abstract
Work was initiated on the design and development of an experimental ultraviolet transmitter to demonstrate its applicability in long-range space communications. The approach to the objective is through the development of a coherent source, i.e., a Laser operating in the ultraviolet range. Two distinct modulation techniques, intensity modulation and polarization modulation, will be utilized to impress information on the system. Potential applications of the system are discussed on the basis of the derived range equation and a review of the state-of-the-art of detectors is presented as a guide for utilization in receiver systems. It was established that a Laser system consisting of an all-quartz discharge tube and external mirrors is a satisfactory vehicle for further development work for an ultraviolet transmitter. With the care exercised in the vacuum processing of the tubes, Laser operation for over 150 hrs without any noticeable deterioration was observed. (Author)
