Hargrove, Logan Ezral, 1935-
Oral history interview with Logan Ezral Hargrove, 1985 June 25.
Michigan State University, Ph.D 1961; thesis on interaction between light, sound, and nonlinear acoustics (Prof. Hiedmann). Research job with Bell Telephone Laboratories, 1962; discusses freedom to pursue research directions as characteristic of the laboratory; begins work on mode-locking. Origins of collaboration with Richard Fork; Fork's attempts to find beats between two laser modes, difficulty of running He-Ne lasers stably with two modes (Willis Lamb). Documentation on mode-locking research; details of collaboration with Fork; Fork's contribution of diagnostic equipment and its role. Experiment with J. Courtney-Pratt to make real-time records of laser output. Detailed discussion of artifact given to Smithsonian Museum by Fork and its probable place in the sequence of experiments. Discusses DeMaria and his team at United Technologies; Moro Didomenico's work at Bell Laboratories. Cornell Electron Devices conference (Yariv, Steve Harris); New York Academy of Sciences conference on lasers, 1963 (Gürs and Muller). Good work atmosphere at Bell Laboratories; publishes trilogy of papers with Fork and Pollack. Follow-up researches on mode-locking; frequency-shifting (Michel Duguay), extension of acousto-optic modulation work. Moved to Crawford Hill, is discontent with more applied orientation, leaves Bell.
