During the overall period of this contract research on laser physics and laser technique was carried out in the areas of laser mode locking and the generation of ultrashort pulses, dye laser pulses, hollow-cathode gas lasers, and optically pumped gas lasers. These results are documented in a comprehensive bibliography of 14 scientific journal publications. The first visible optically pumped molecular vapor-phase laser was operated. Rotational relaxation and triplet state effects in dye lasers were studied. An antiresonant ring interferometer for laser mode locking and cavity dumping was invented. The transient build up of mode locking in simultaneously Q-switched and mode-locked lasers was analysed and experimentally confirmed. During the final year of the program significant advances were made in the optically pumped 546.1 nm mercury laser. Sealed-off laser tubes that should have long shelf and operating life were developed. Operation using dc-excited field-replaceable discharge lamps was obtained. This laser appears very promising as a general purpose low-power green laser source, as a potential visible wavelength standard, and as a laser medium for ring gyroscope applications. Author
