Abstract : The report briefly summarizes research conducted in several areas of importance to laser theory and application. Precision methods were developed for the measurement of atomic lifetimes ranging from about one microsecond into the sub-nanosecond region. Lifetime measurements were reported for a large number of laser transitions in the noble gas ions (Ne II, Ar II, Kr II and Xe II), with limiting errors in the order of a few percent. Detailed studies of charge exchange and Penning excitation processes were reported in singly-ionized zinc and cadmium lasers, and many new cw laser transitions were reported in Zn II. Theoretical studies of scanning lasers, saturable absorber effects and frequency of stabilization methods were also conducted. Theoretical and experimental measurements of line shape analysis were performed and measurements reported for many noble gas ion laser transitions.
