Ph.D. thesis under Charles H. Townes, with research (in collaboration with Herman Cummins) directed towards achieving an operating laser. How Abella became Townes’ thesis student and joined Cummins in 1959 in research on the potassium laser.
Interview discusses the "delayed choice" experiment carried out in the first part of the 1980s. Also touches on Alley's relations with John Archiball Wheeler, equipment invented for the experiement or adapted for it from previous work on lunar ranging and atomic clocks, and the experiment's role as precursor to Yanhua Shih's experiments using photons apron spontaneous parametric down convers in.
Beginning of studies in molecular spectroscopy at Moscow Institute of Physics (MIFI) (1948). Invitation to Lebedev Institute (FIAN) by Mikhail Aleksandrovic Leontovich, head of the lab and MIFI theoretical physics department. Early radio spectroscopy work there with Aleksandr Mikhailovich Prokhorov using synchrotron. Inadequacy of low sensitivity equipment leading to development of maser-laser technology. Use of CsF molecule to solve problem of increasing the resolution of microwave frequency region.
Research on nonlinear optics at the University of Michigan, 1961 to 1964, laser education at Berkeley, 1964-1966; color centers, laser damages, and dye lasers at Raytheon, 1966-1973, and medical applications at University of Southern California, after 1973. Experimental laser techniques and their evolution and the institutional context of research at each of these sites. Also prominently mentioned are: John A. Armstrong, Nicolaas Bloembergen, Colin Bowness, William B.

Summary of work and development of light emitting diodes (LEDs) and diode lasers done in the 1950s and early 1960s at Sylvania Research Laboratories, and at General Telephone and Electronics Laboratories, 1961-1964. Semiconducting Compounds Group investigates intermetallic compounds, especially GaAs and HgTe in the 1950s. Group joins the Battelle Memorial Institute group, 1957. Group effort devoted to GaAs from 1958. Group leaders discussed, Don Wahl, Henry Minden, and Sumner Mayburg. Work prompted in part by Heinrich Welker's 1952 report on preparation and properties of III-V compounds.

Spectra-Physics; its founding; role played by John Atwood of Perkin-Elmer; the 1.15 micron and 6328A helium-neon lasers; relation with Bell Laboratories scientists; Bloom’s role at Spectra-Physics; Spectra-Physics’s transition from a technologically to commercially oriented firm; the 3.39 micron helium-neon line; consultant at Coherent, Inc.
Bowness was technical director of the Raytheon division that placed the company's lasers and laser systems on the commercial market starting in the early 1960s. Here he discusses the interaction with the Research Division that brought the ruby laser to the attention of his section (Special Microwaves Devices Operation [SMDO]); the availability of components and accessories; early military and commercial markets.
Joined Bell Telephone Laboratories, 1959. Collaboration with John H. Sanders; initial motivation to study curved end-mirrors for laser resonators; interactions with Willard D. Lewis and James Power Gordon; demonstration of curved mirrors at March 1961 Berkeley conference.
